    If anyone recalls i have been working with Jim Williams on a Royer design - which he whipped up in an afternoon after hearing some basic specs...

    Attached are some images of the physical unit he sent - very hack/slash friendly - which is right up my alley.

    He also attached a hand written write up (on graph paper) and a hand drawn schematic.

    As i document this in a more stable media (ie - digital schematics and a word document write-up etc) i will add to this thread.

    This is PROOF positive that in order to be a really good engineer you dont need to be a pristine assembler, only have knowledge of how electricity and electronics work - the rest is personal preference.

    Really good see. I love to see the way that masters can do things well with no flash or glam. I like how Bob Pease writes things on the backs of envelopes during his webinars. Thanks for posting.

    no problem!

    I attached a pdf of the circuit - drawn in OrCAD Capture for documentation purposes at work.

    I have a few questions for Jim which i will hopefully get to ask tomorrow afternoon, or Friday by the latest - mostly related to the LT1122 and LT1366 voltage rails - and if there was any supply bypassing he used on them. I am not 100% sure that they both run off of +/- 15V not clear from the schematic or breadboard.

    Also, the biasing on the LT1366's (driving the PNP) + terminal is odd looking to my eye.

    Also i dont know how to tap the high voltage out for use on external components - or rather, what he would suggest. I cant imagine clips would be wise.
