I’m in the process of rehabbing this Realistic I’ve had for a couple of years. 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. Now trahsistor I’ve started I found one channel must have failed because there were a lot of replacement components.

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. At this point what would you do?


Leave the transistor that’s there? Are the clamps available anywhere? I couldn’t find any.

Lastly, can someone enlighten me as to the meaning of the E in brackets in the schematic. 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? It’s tricky to set the bias up on the BinkmanSep 5, The replacement is a TCG Google returned Talon electronics as a source.

Surprisingly they also the 2sd for 45 cents. Dataseet for the E nlightenment! Thanks Glen, I will check out your recommendation. I posted this same question on Diyaudio and and received good advice from there as well. Was advised to replace the trimmer pot VR Hopefully, this post will aid others who wish to restore this model. CCW but I transisor wire in a cw plus v pot in reverse. Thinking of buying some extras, too. BinkmanSep 6, Glen, The ZTX looks like a very good match.


Because of this discussion I’ve noticed more issues.

The repairing tech used a TCG to replace the 2sd on the heat sink. There must have been a lot of those lying around.

Check a few traces in last pic. I know it’s hard to determine good solder on a pic with lighting and all. Good once over visual before you repack it. BinkmanSep 8, I use Chem-Wik to desolder and an industrial grade solder made by AIM for surface mount applications.

That and a little RS flux. You must log in or sign up to reply here. Share This Page Tweet.
