Looking for a second UTC S-30 to complete a pair. However if someone has multiples, and the price is right I would be interested.
Also looking for a few much more obscure UTC bits for completing a stereo pair, from US military com gear... there is a 5-digit designation, Ive never been able to find any list or catalog of these things... I'm not imagining I'm actually gonna nab one of these, but one can dream... more like a "check ebay twice a week for 7 years" kinda thing but...
UTC "68571" plate and filament (630vct)
UTC "71432" tube output (5k pri)
UTC "63832" choke
No TF.......YY typical military designation on those, so, can't match other manufacturers...
Acquired NOS & boxed, not pulls, so I don't even know what units they came from.

Holy cow, I got it! Someone listed a pair on fleabay for a reasonable price! ($85 ea).
I wonder if they read this thread... anyways, a happy conclusion to my search. I just really wanted to go choke input to drop voltage, rather than running the whole amps current through dropping resistors. Been looking for alternative plate transformers with slightly lower voltage, to no avail because once again - pairs. Trying to do matching monoblocks. I plan to use all UTC iron on these babys, so, you know, gotta keep it matching...
I'm glad it came up while I had the money!
I'll try to make that 3rd work in a stereo amp (175mA rated) but chances are I'll be looking for one again in 2 or 5 years...
