I donated an audio amp CML 50171 (part of JR-1 sonar, fits in a 3 bay rack cabinet, Rectifier unit below) to a museum boat and one of the volunteers buffed all the metal tubes in it to a nice shiny polish.........Now they want to test the tubes, of course because "it doesn't work". The cases were all stamped w/ the number 60 on the annular ring, and they are convinced they are all #60's of course. That means nothing, IIRC.
This is probably late 50's mid 60's vintage gear.
2 tubes are on ceramic sockets, the other pair have rubber isolation brackets for microphonics. All we get is a hum...........
Any leads out there?

Off to test the TCS now. I made them promise NOT to ^%&* with it..................
