Are the clamps available anywhere? Check a few traces in last pic.

I know it’s hard to determine good solder on a pic with lighting and all. The repairing tech used a TCG to replace the 2sd on the heat sink. I posted this same question on Diyaudio and and received good advice from there as well. Hopefully, this post will aid others who wish to restore this model. Surprisingly they also the 2sd for 45 cents. Was advised to replace the trimmer pot VR 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?


Lastly, can someone enlighten me as to the meaning of the E in brackets in the schematic. Do you already have an account?

I couldn’t find any. I’m in the process of rehabbing this Realistic I’ve had for a couple of years. There must have been a lot of those lying around.

Good once over visual before you repack it. That and a little RS flux.

datssheet Thanks for the E nlightenment! Now that I’ve started I found one channel must have failed because there were a lot of replacement components. BinkmanSep 5, BinkmanSep 6, At this point what would you do? Log in or Sign up.


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. Because of this discussion I’ve noticed more issues.

Yes, my password is: CCW but I can wire in a cw plus v pot in reverse. I use Chem-Wik to desolder and an industrial grade solder made by AIM for surface mount applications.


Thinking of buying some extras, too. It’s tricky to set the bias up on the The replacement is a TCG No, create an account now. Your name or email address: You must log in or sign up to reply here.

BinkmanSep 8, 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.
