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

Give to me for proper disposal. I'll even pay shipping. :D

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!
