TO-3 SYMASYM

Jump to Latest
#121
Gentlemen,

I could get hold of another set of TO-3 - and driver transistors for the TO-3 SYMASYM.

I am able to sell you these transistors (4 pairs of MJ21193 / MJ21194 and 2 pairs of MJE15034/MJE15035) for 26€.

The transistors are new, have not been used before and are 100% authentic OnSemi.

If somebody of you is interested to buy them, please give me a PM.

Best regards - Rudi_Ratlos

When I'm ready, you'll get pics. But this will take a while. I still have to buy some missing parts. At the moment I'm busy with matching the MPSA18 Transistors.

BTW, if somebody needs some matched pairs, I can help. I was quite lucky with my MPSA18 package. A first quick Test showed a very low tolerance. Seems, there are a lot of pairs with 1% or even better...

regards,

Chris

I am sorry, Joe, my old friend, I do not have any PCB left.

Maybe there is some interest in a 3rd round, but let us wait for the feedback of the ones, who are going to build the TO-3 SYMASYM, before.

I wish you all success with your build.

I soldered and tested the "Soft-Power-ON" - PCB yesterday.

An externally hosted image should be here but it was not working when we last tested it.
