I am working on a T@R PA amp either a K200A-5 or K200B-5. I'm not absolutely sure because of a damaged model sticker. My problem is with the PC802 reverb/summing board. The schematic(s) I was able to find from other posts are not the same as this PC802. This rascal has 12 transistors and +/- 25 volt rails. I'm going bonkers trying to signal trace this thing and I hope someone who has the schematic can verbally walk me through it.
I've had good success with Fender, Gibson, Peavey etc. but this is my first Kustom. Any thoughts will be greatly appreciated.
Incidentally, I'm happy to be the newest member to the forum.

Welcome to the place. The A-series heads have the +&-25vdc preamp boards, so I would think that yours is an 200A version. I don't think that I have seen a schematic for an A-series reverb mixer board. Maybe one of the other guys here has one.
In any case, what is wrong with your amp?

Sometimes being in a big city, it doesn't get any better.
The SE4002 is pretty generic, so almost any transistor will work as a replacement.

You and me both with the new micro stuff brother! but not even that stuff so much,heres one for ya, the other day I had a 2 year old fender amp that I had to fix as it needed its input jack to board connection resoldered.
I got the amp all apart and then thought that all I had to do is get the main board out flip it over and touch up the solder connections, the amp is made so that you need to remove the power transformer to get the board out.Well dont you know I was WRONG! It turns out you can not even after that get the board out as they must fold up the front and rear section of the chassis once the dam main board is in, or they have a spreader that gives you than last 3/8s inch you need to loop the board up and out!!!
I COULD NOT BELIVE IT!!! I had to tell the customer I could fix it if I could only get it apart all the way, which is something I never had to do in all my 45 years of repairing gear!
Just unreal!!

I could not agree more with your that last statement more!!!
I have as of late here in the summer I have to deal with near brown out conditions with the power grid here due to governments energy plans, or lack their of, but yet they spend and freely waste more of yours and my tax dollars on not letting me or you have a Gibson guitar to play in the dark of a brown out.
ALOT more people better wake up to all this over the limits government on both the federal and local levels or in about 3 to 4 years where going to be just another 3rd would nation in decline!
