I found these tubes from my garage.
However, I am not familiar with most tubes.
Can these applied to amplifier?
Cheap or expensive?

thanks

the 1B3/1X2's are more or less useless (HV low I rect)

50L6 is an output pentode, ok for 3 or 4 watts

6SA7 is hept', useless as far as you are concerned..

12SQ7 is high gain triode + diode, could be useful for gain

6AL5's are good for christmas lights.

6AG5 is a little sharp cutoff pentode. looks ok in triode mode though.

12DQ6 and 6KD6 are big sweep tubes, useful for output stage

I don't know a bunch of those off the top of my head, if you made a list and classified them as to triode/pentode/power device etc. we could start picking over the carcass, so to speak, and design something weird. 🙂

Well, my wife finally begins to drive me crazy for these valves.....
If you do want to have them, reply within an hour or I will put them into trash box. You just pay for shipping.

Colt45! What a joke for Xmas Light Tube!
