Sylvania 1-076 arrived!

I checked the tubes. Out of 32 tubes only the 6T8 was bad.

I had to repair a Sencore SuperMack CR41A before I could try to test the 10MP4. I tried it out on a 5AXP4 and 10BP4 that I had tested previously and it worked well.

When I tried it on the Supermack the filament lit up but I couldn't set the balance or read any emission. Small wonder. The CR41A measures emission through G2. There is no G2 in a triode. They must have made a mistake when they listed the 10MP4 in the settings booklet.

I'll have to make up some flying leads for the B&K to test it. I'll only be able to test the emission though.

The CRT base was loose so I was focusing on it while removing the socket. I didn't notice that I had a finger pressed against one lead and the solder tab broke off of the pin socket. I can solder it back onto the pin socket, but it might be nice to replace the socket.

Can anyone tell me where to look for a CRT socket? It would be the same as used on a 12LP4.
