I know it’s likely to be unobtainium, but I’m looking for an ST-107 tubester.
The one in my 75S3C appears to have a problem — with the ST-107 in place, gain is low and the meter will not zero (it bottoms out around S-9). A 6BA6 in the V7 spot fixes the problems, but I’d like to put a tubester back in there if I can find one.
If you have a whole 75S3B/C tubester set and don’t want to break it up, I’d consider buying the whole thing depending on $$.
Thanks .. Grant NQ5T
