Hi there,
I bought some NOS tubes several years ago, hopefully I can make some decent stuff out of them in the rest of my life. Here they are:
"Small" ones:
27 (Sylvania)
5687 (TungSol)
6J7 (Philips/RCA)
6SJ7 (RCA)
6EJ7 (Brimar)
6J5/G/GT (GE/Mullard/Ken Rad)
6S45PE/6C45Pi (Russian Military)
6H30pi (Russian Military)
"Middle" ones:
6EM7 (GE/Sylvania)
6V6/G/GT (Amperex/Unknown '40 British Military/GE JAN/RCA JAN)
"Bigger" ones:
811 (Sylvania JAN)
SV811-3 (Svetlena, this is not "NOS")
6080 (Philis/GE/Sylvania)
6AS7GA (RCA/GE)
6336 (Cetron Graphite plates)
Rectifier:
6X5GT (RCA)
5Y3GT/5Y4GT (GE/Sylvania/RCA)
82 (RCA)
5R4GY (RCA)
GZ37 (Mullard)
I've been thinking of several possibilities:
Line stages:
1) 27 with CCS load
2) 6J5 with CCS load
3) 5687 with choke load or OPT
4) 6S45PE or 6H30pi with OPT
Small amps:
1) 6H30pi single tube/single stage SE
2) 6S45 single stage SE
3) 6EM7 alone SE or PP
4) 6J7 (or 6J5) -> 6V6 SE or PP
Bigger amps:
1) 6J7 -> 6V6 -> (6080CF) -> 811 SE
2) 6EM7 -> SV811-3 SE
3) 6SJ7 (or 6EJ7) -> 6V6 -> 6080 or 6336 PSE or PP
4) 6EM7 -> 6V6 -> 6336 OTL
Other usage: 6080 and the likes as rectifier....
With the list, it seems the "small amp" group would be the most fun to build & use. And there'll probably be much trouble to deal with the "bigger amp" group. Maybe I'll need some more "middle" tubes for proper driver stage....
Your suggestions & experience sharing will be highly appreciated
