Despite appearances I am working on the tutorial (off-list)

I'm sure of it HP I know you do! You're being too intense as usual so relax!

HP I pleased by attitude of TS of soldering station thread cuz he's not the collectivist minion follower puke! Instead of cave and purchase overpriced product he takes initiative and builds for himself! So he's good example for put principle before convenience so I vote likes to all his posts on thread! If somebody po'ed I say tough! My votes are my call! But don't worry! I keep promise not put the likes on your posts! HP you behave until I back to stay cuz I expect to see some work done, young lady

 

Hey Aleph! How do?

I pleased by attitude of TS of soldering station thread cuz he's not the collectivist minion follower puke! Instead of cave and purchase overpriced product he takes initiative and builds for himself! So he's good example for put principle before convenience so I vote likes to all his posts on thread!

First off -- let it be known that I wholeheartedly concur with your sentiments and for the precise reasons you offer!!! -- That said, a possible rationale for objection to rewarding 'initiative' (or other qualities of character) via 'carpet likes' lies in the fact that, properly 'granted', 'likes' should be about the post as opposed to the poster -- IOW, in the eyes of skeptics, 'liking' every post by a specific member smacks more of zeal than affirmation...

If somebody po'ed I say tough! My votes are my call!

I have no argument with that so long as the 'like-ee' has a say - IMO if someone objects to a 'like' on his/her post courtesy demands its removal --- Ditto for 'following'...

But don't worry! I keep promise not put the likes on your posts

Good deal!!!! I have no desire to be perceived as playing Edgar Bergen to your Charlie McCarthy --- or, infinitely worse, vice versa!!!

Please don't 'get me wrong' --- I enjoy granting and and very much appreciate receiving positive feedback via the 'like' feature -- It must, however, be used conscientiously if it's to have any meaning...

You're being too intense as usual so relax!

HP you behave until I back to stay cuz I expect to see some work done, young lady

Is it just me or is there an oxymoron in here?

All the best
HP

 

HP Plz post ltspice simulation schematic of circuit in pic in post 197. It okay if omit ma meter and mov cuz hand drawn means not in library? So I say plz put doublers just in series then I monitor current with probe tool. For now I say use 20Meg resistor to model tube with cathode temp set for 5ma anode current when electrode voltage is 100kv. HP I'm happy to be back only tired

Hey Aleph -- Please don't think I'm ignoring your request! -- LtSpice has got me again! --- It works flawlessly for unbalanced arrangements however 'it no like' the balanced/split configuration --- Anyway, inasmuch as I also wish to develop 'LtSpice literacy', I have a request in to the General Chat forum (q.v.) --- I know there are some real experts on these fora -- but being Friday evening - patience will likely be required!

All the best

Hey @Aleph(0)

The attached schematic ain't perty --- Howbeit it works both 'in vivo' and 'in vitro' if you will --- Now if I'm ever to finish the tutorial - please cool it with the 'assignments'!...K?

 

HP I say that's perfect! I don't know why you think it's ugly? I say it astonishing that 1nf for capacitors at low frequency of 30khz is enough capacitance for low ripple and fantastic load regulation! I look and It clean enough to 60ma which is 6kw! Not saying transformers would survive but that's not point!

Now if I'm ever to finish the tutorial - please cool it with the 'assignments'!...K?

HP I hope you not take my scoldy talk seriously? I mean it when I say no pressure!

 

HP I say that's perfect! I don't know why you think it's ugly?

I'll grant you it is purely aesthetics --- The current indicator grounded at one end 'strikes a note' of asymmetry...

I say it astonishing that 1nf for capacitors at low frequency of 30khz is enough capacitance for low ripple and fantastic load regulation!

Indeed! In this case I was quite pleased to discover that I had miscalculated and that LtSpice was correct (for a change)!!! --- $35 apiece caps compare quite favorably to $750 caps on the 'economy front' --- I only wish I'd discovered my error prior to purchase of those forty 100nF N4700's Oh well! $30K worth of large value EHT caps might be seen as a good investment in light of the pending increase in manufacturing costs 'secondary' to ROHS

HP I hope you not take my scoldy talk seriously?

No worry of that -- That's the 'cool' thing about consanguineous family -- Our sentiment as regards each other is unconditional - even should we ever manage to seriously tick each other off -- the 'frost' would be short lived!

All the best
HP

 

Moved to Post #247

 

This post intentionally left blank

 

@Aleph(0) --- Pursuant of my email message of 10 Nov 2015 6:33:17 CST:

It's all set! -- I have completed the 'first draft' (excepting the introduction) - Please copy post #208 then re-post it -- thus creating 'your own copy' (i.e. a copy to which you have 'edit access').

Please annotate your edits as follows:
For reference, it is preferable that you leave the original text intact but stricken --- Example: {s}Original Text{/s} (but bound by '[' and ']' instead of '{' and '}') --- The stricken text will display thus: Original Text following posting of same...

Please annotate all edits via bounding the stricken text and any notes with '$$$' and the revised text with "###"

In the case of minor spelling/punctuation/capitalization or wrong word errors --- Please 'unbold' the 'afflicted' line (if necessary), strike it, bold the 'offending' text only then bound the line...
In the case of a generally 'hopeless' line -- please unbold it, strike it, bound it, and annotate it:

Inasmuch as the former would seem self-explanatory I offer two examples of the latter...
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Example 1:

Annoying text:
"irregardless the application, he Eht coil must bear the product of the amperage and voltage applied to it but current can damage the wire all by itself"

Unbold:
"irregerdless the application, he Eht coil must bear the product of the amperage and voltage applied to it but current can damage the wire all by itself"

Strike, bound and annotate:
"$$$irregerdless the application, he Eht coil must bear the product of the amperage and voltage applied to it but current can damage the wire all by itself$$$"
$$$Deletion notes: Instruction in fundamental electrical relations falls outside the scope of this tutorial - moreover, 'voltage' is problematic, and 'amperage' is appalling -- as are the 'pediatric' tone and copious errors! -- You can do better!$$$

Revise and, if necessary, annotate:
###Regardless of the transformer's application, both power handling and current carrying requirements bear consideration###
$$$Revision notes: In avoidance of confusion, I prefer 'requirement' to 'capacities' in this context - the resulting 'object/subject inversion' does not alter sense or intent.$$$

Example 2

Annoying text:
Be careful with PTFE because if it gives off dangerous fumes when it gets overheated"

In this case the original text is not bolded so....

Strike and annotate:
"$$$Be careful with PTFE because it gives off dangerous fumes when it gets overheated$$$
$$$Deletion notes: Informal, imprecise and altogether awful!!!$$$

Revise:
###Owing to the significant toxicity of PTFE pyrolysis products - caution is advised###

Got it...?

OBTW if you're 'itching' to revise the revision examples -- that can only mean you're in the proper proofreader spirit

All the best
HP

PS --- Inasmuch as I seem to recall that you cannot get the format bar working:

BTW The format bar is far and away the easiest way --- please give it another try

1) Select the text to be formated
2) Left click on the desired format option
If you have difficulty please speak up so's I can venture to 'orange land' and attempt to sort it for you!

If all else fails - here's how it's done 'manually'

In all cases substitute '{' and '}' with '[' and ']'

To bold
{b}Text{/b}

To Italicize
{i}Text{/i}

To Underscore
{u)Text{/u}

And, again, to strike
{s}Text{/s}

Note 'reversing' formatting (sans the format bar) requires deletion of the HTML directives via the 'BB Code' editor...

 

@Aleph(0)

A member of the Moderation staff has kindly offered to assist us (via a managerial 'workaround') should we 'hit the wall' as regards post size limits --- So... Should you encounter difficulty submitting your copy of the tutorial-post following editing -- Please tell me about it

All the best
HP

 

This post is place holder only

 

HP tnx! I copy tutorial as you say so will be able to proofread maybe Sunday sorry because of delay Is like you say not enough hours on clock for what I like to do which means proofreading too!

HP you give examples for redaction notes

$$$Deletion notes: Instruction in fundamental electrical relations falls outside the scope of this tutorial - moreover, 'voltage' is problematic, and 'amperage' is appalling -- as are the 'pediatric' tone and copious errors! -- You can do better!$$$

$$$Deletion notes: Informal, imprecise and altogether awful!!!$$$

Ha ha! I do agree but can't be so rude from my house of glass

Ok I try formatting from bar:
Bold
Italic
underscore
All of above
Can't find strike button so manually like you said
Strike

HP Sorry I go now VPN keeps dropping me cuz of high winds excuses excuses!

 

HP tnx! I copy tutorial as you say so will be able to proofread maybe Sunday sorry because of delay Is like you say not enough hours on clock for what I like to do which means proofreading too!

No problem! Howbeit please check 'my copy' when you start, such that you may 'sync' yours in the event I make further changes in the meantime... OBTW -- I notice some of the formatting failed to 'make the trip' -- while such would seem of little consequence for proofreading purposes, if you want, I can email a proper (i.e. 'BB Code') copy (for identical display upon posting)?

for what I like to do which means proofreading too!

You're easily pleased!!!

Ha ha! I do agree but can't be so rude

The tone of my examples is way too kind! --- Moreover, the 'glass house' metaphor is inapplicable to you inasmuch as your 'brand' of 'numpty-speak' is mere affectation

Ok I try formatting from bar:

Remarkable! -- Your results couldn't have been better had you attempted it from the 'coffee house'!

To wit: By Jove! I believe you've got it!

Can't find strike button so manually like you said

It seems 'strike' is not available from the format bar - (on original style view anyway --- I can't say for certian with 'orange view') -- IOW - all's good!

HP Sorry I go now VPN keeps dropping me cuz of high winds excuses excuses!

We've got it here too and with 'DSL' glitches --- Though I can't imagine why weather (apart from lightning) would affect a VPN?

All the best
HP

 

HP I sorry for digression but plz say what connectors best for gen purpose HV power supply? I did like you suggest and repoted 60hz transformer from scraped xray head so 0 to 130kv with 240v variac in primary. By 40kv I have 800w loading cuz of 20ma corona leak from ceramic bushings and it flashes over when increased for 60kv And it's not convenient type of connection anyway I ask also what you use for load when test your double doubled royer psu cuz 10 Megohm resistor for 1Killowatt hard to find?

 

By 40kv I have 800w loading cuz of 20ma corona leak

Indeed, despite dearth of 'drama', corona losses can be very 'heavy' -- When troubleshooting radiography 'generators' (or other EHT PSUs) for insufficient output EMF, the difficulty is occasionally localized to corona losses of several tens of mA (said discharge being but poorly perceptible at room level illumination) -- Such is a near certainty where the presentation is that of output EMF tracking as expected to Ca. 35kV, whereafter increased drive occasions but negligible effect on output - Kudos on your intelligence and powers of observation - most folks (including myself) overlook/underestimate the significance of corona at 'first blush'...

And it's not convenient type of connection anyway

You didn't hear me say it was!

what connectors best for gen purpose HV power supply?

IMO Federal Standard Connectors (CIP receptacles/'wells') are the only way to go! --- Yes! I know! They require a lot of space! Even so, the advantages more than compensate for said inconvenience!

I ask also what you use for load when test your double doubled royer psu cuz 10 Megohm resistor for 1Killowatt hard to find?

Aleph! -- You, who so well know the nature of my soul would suppose that I should seek recourse to so pedestrian an expedient as a conventional resistive load!? - for shame!!! --- Actually, the load is, as the pious folk are wont to say "In The Mission Field' --- Case in point, a FA w/cathode temperature set for an anode current of 10mA --- Utilitarian but effective!

With profuse apologies to EA Poe and pious folks everywhere!

Best regards
HP

 

@Aleph(0) (and, as always, any/all interested parties)

While you, of course, are familiar with Federal Standard Connectors, it occurs to me that some present or future readers of this thread may not be... Moreover, I'm uncertain as to whether you've seen same outside of their 'native habitat'?

Note that the pictured connector components are those of a standard Federal connector (applicable to a symmetrical ≤ 150kV "generator") featuring 5 inch plug/well-depth. Note the three small receptacles/pins in the 'detail' (penultimate and ultimate) images --- Which being provision for the two filaments and filament common -- The 'anode side' of the "generator" (i.e. PSU) and tube housing tie said leads together...

Hope someone finds this of interest!

Thanks HP! Believe me or not I was thinking maybe should use Federal Standard Connectors and be done with it!
Now I'm saying what's with Bovie and big a$$ electrolytic caps? Are you being a mad scientist at work?

HP I proofread tutorial but without framing intro I'm at a loss for critical perspective so plz write intro then I review whole tutorial but I warn you that I'm weak at punctuation too

 

Thanks HP! Believe me or not I was thinking maybe should use fed connectors and be done with it!

Indeed, it really is the best approach -- Granted the wells take up plenty of 'real estate' but then that's the nature of EHT assemblies in general...

Now I'm saying what's with Bovie and big a$$ electrolytic caps?

The capacitors came in handy for 'posing' the connector components -- The ESU was just there... What's the problem? Are you requesting that I set up a studio for the express purpose of creating these illustrations??? --- Shall I chew your food for you as well???

HP I proofread tutorial but without framing intro I'm at a loss for critical perspective so plz write intro then I review whole tutorial but I warn you that I'm weak at punctuation too

Ok... I'll finish the 'draft' -- be advised, however, that continued alacrity on my part will be in direct proportion to your demonstration of same!

Best regards
HP

 

HP plz don't question my sincerity! It easy to say suggestions welcome but nobody likes negative criticism when it happens! So I wait until I have whole context before I put neck on block Now I'm asking you to read my post about ltspice cuz what I'm doing wrong is not obvious to me
