Naggys offered some years ago and I saw some pictures on AlieExpress but can't seem to locate them now
I really need modules but if that will fail I will buy a board with modules . Original modules are epoxied and probably impossible to fix
Ok, I had one of those amps many years ago. If you remove the module in it`s entirety, you can just substitute the doble JFET, and the other transistors are MPSA42-92.

It's a radio🙂. You mean , it's possible to take apart that module and fix it ?I tried to pry the case of A1 module and it looks like it's filled with epoxy
No, you can`t fix the module, but you can remove it. And do as mentioned. Or, you might want to be very transparant and show what you have, and what you need. Maybe that`s best.

I am transparent. I need replica of Goldmund A1/A2 modules as pictured above. Two minimum. I already removed the original ones because they are shot.
It's unlikely that any DIYer will have the modules alone because they were sold with the board which you also have , That's why I posted about the board and modules. They used to be available on AlieExpress but not anymore or I'm unable to find them. Also, the modules are used in Goldmund radio not a preamp or amp. Goldmund used them everywhere.
If you're willing to sell the board I would be interested, if I won't find separate modules which are exact fit in the socket that Goldmund used.
Chinese DIY board can be modified to use modules in a form of your blank PCBs hard wired to the circuit. Original Goldmund board cannot without becoming absolutely worthless.
