SSRP test fixture

Tony had a great idea for a SSRP test fixture, so i intend to design this for him and anyone else that needs it for that matter. Perhaps do a group buy.

Octal and Noval double triodes where imagined, i wanted to use PCB material for the top plate, and use M4 standoffs, around the corners. The belton sockets dictate that the standoffs are about 15mm with a washer approximately 1mm thick.

The bottom PCB will contain the sockets and connections for banana jacks.

Heater1 will be connected to the ground plane, and pin 9 of the Noval double triode socket.

I will add another hole in the top plate for a little switch, that will switch pin 5 between H2 and ground, so the fixture is usable with ECC88 and ECC83 (just an example many, many more tubes will fit.


Dimensions are 100x100mm.
