First off... i am new to the forums and new to electronics in general. I have been doing a lot of reading on components and how they work and what they do... so far so good.
I have been repairing a graphic equalizer (kenwood ge-7030) that needed 5 new electrolytic's from what i think was maybe a mains spike... two main caps on the ac line in... and every 10uF cap on the main board either had a low reading or non at all... it is working fine now.
As a project i have been reading about changing capacitors and resistors to higher quality caps and metal film resistors of better quality to tighten the tolerances and hopefully improve sound... the equalizer did not cost me anything so its sort of a little project of tinkering so i have something to focus on while i am learning.
I have come across what i believe to be either metalized/polyester film capacitors and cannot find the markings or a chart anywhere that describes what the markings mean... i am using an online calculator at the min just to punch in the 3 digit numerical code and see what the value is... then check it with a test meter... but i am stuck with this one as i am new and hoping some one here with more knowledge could help me out.
I have attached a picture... while looking there is actually another ceramic disc cap i cannot identify... i know the values of the cap's but not what the other markings mean...
the two different caps in question are the (L274) and the (SR183K)
Any info/help would be very much appreciated... i have been searching google for a full day and cannot find anything on these caps... or if anybody knows of a link to a site where i can read up on them would be even better.
Cheers.
