SOrry, I misspoke, by 'repair' I meant
'replace'. Though my father had
an 01 (not 01A) tube with I swear an RCA base and a Westinghouse
envelope (seal on top of tube) or converse. I lost it as a kid (ouch).
This is because Westinghouse made many (most, I think) of RCAs 201s. GE
made them as well.
Prototype development I'd say.
Have you obtained all of the tubes you need? I noticed on your websight
you mention using "Red Series" tubes. As you probably figured out, those
(RCA Red Line or Bendix Red Bank) are pretty expensive.
