A friend of mine has a box of Nuvista tubes, 8393 and 7586 that he

Anyone know where we can get an adapter or even a tester with the
adapter built in?

TIA


Aren't those Nuvistor tubes? Used to find those in TV tuners of lore.
Might try rec.audio tubes. Some of those guys are pretty sharp and may be
using nuvistors in audio amps.


My 60s era Navy Surplus tube tester has Nuvistor sockets.
