I’m in the process of rehabbing this Realistic I’ve had for a couple of years.

2SD400 Datasheet, Equivalent, Cross Reference Search

Are the clamps available anywhere? 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 6, There must have been a lot of those lying around. Thanks for the E nlightenment! Do you already have an account?

Yes, my password is: I use Chem-Wik to desolder and an industrial grade solder made by AIM for surface mount applications. Discussion in ‘ Solid State ‘ started by mikte15Sep 5, Leave the transistor that’s there? Google returned Talon electronics as a source. The replacement is a TCG Surprisingly they also the 2sd for 45 cents. Share This Page Tweet.



BinkmanSep 5, The replacement is not a TO package and there is no stock mounting clip like the other channel right. I know it’s hard to determine good solder on a pic with lighting and all. CCW but I can wire in a cw plus v pot in reverse. Thinking of 2dd400 some extras, too.

Was advised to replace the trimmer pot VR Your name or email address: 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. BinkmanSep 8, Thanks Glen, I will check out your recommendation.

At this point what would you do? Check a few traces in last pic. Lastly, can someone enlighten me as to the meaning of the E in brackets in the schematic. Glen, The ZTX looks like a very good match. Hopefully, this post will aid others who wish to restore this model. That and a little RS flux.


Because of this discussion I’ve noticed more issues. Good once over visual before you repack it. I couldn’t find any. 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.

It’s tricky to set the bias up on the No, create an account now. Log in or Sign up. 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.
