I played it a bit after I bought it but it sounded a bit off so I stowed it away until I was ready to do a full recap.

Yes, my password is: I use Chem-Wik to desolder and an industrial grade solder made by AIM for surface mount applications. That and a little RS flux. Because 2ad400 this discussion I’ve noticed more issues.

Log in or Sign up. I posted this same question on Diyaudio and and received good advice from there as well. Now that I’ve started I found one channel must have failed because there were a lot of replacement components.


Was advised to replace the trimmer pot VR Do you already have an account? Thanks for the E nlightenment! I know it’s hard to determine good solder on a pic with lighting and all. Are the clamps available anywhere?

Google returned Talon electronics as a source. Surprisingly they also the 2sd for 45 cents. Good once over visual before you repack it. There must have been a lot of those lying around.

Thanks Glen, I will check out your recommendation. Thinking of buying some extras, too. Your name or email address: Discussion in ‘ Solid State ‘ started by mikte15Sep 5, If it looks good on the boards probably easier to fix maybe but if it’s pretty burned out or looks like it came out of a flood?

BinkmanSep 5, Glen, The ZTX looks like a very good match. It’s tricky to set the bias up on the No, create an account now. I couldn’t find any. Hopefully, this post will aid others who wish to restore this model.

Since none of the components were the same as stock I decided to follow the EW’s advice in this thread and go with On Semi replacements. The replacement is not a TO package and there is no stock mounting clip like the other channel right. Leave the transistor that’s there? Check a few traces in last pic.

I’m in the process of rehabbing this Realistic I’ve had for a couple of years. Transixtor, can someone enlighten me as to the meaning of the E in brackets in the schematic.

BinkmanSep 8, Share This Page Tweet. CCW but I can wire in a cw plus v pot in reverse. The replacement is a TCG At this point what would you do?
