I received a bunch of 6080 tubes from a closeout deal from an old electronic repair shop many moons ago. I originally wanted to use them to create an OTL amp, but after reading up on how inefficient these amps are and they are very finicky, I decided to drop the project.
I don't know what the tubes are worth today. Just toss me a number and if I like that figure, the lot of 6080's is yours.
Thank You,
Geo
