Testing 01A tubes
#1

Anybody know if you can test 01a tubes? There is no listing for them for my Precision series 612 tube tester.
I'm going way back on my next project, a 1925 Grebe Synchrophase MU-1, and would like to know what kind of shape the tubes are in. Should be an interesting project. I've never worked on a set this early before. Looks to be very well made and I've read that they are considered to be the best TRF sets ever designed.
