Hello all,
This is my first post, so please be kind.
My Grandpa was an avid Ham and Shortwave Radio enthusiast. After he
passed, I found a box full
of old tubes in his garage. I would like to gain some knowledge about
the applications of the
various tubes, and ultimately find out if they would have any value to a
collecter. Below is a
complete list, along with what cross reference numbers I have been able
to locate, so far. Any
help with THAT is also much appreciated!
=====================
Vintage Vacuum Tubes:
Count Tube# Cross Reference #'s
===== ===== ===================
8 16A (6AM5)
1 16Z (???)
not sure of these
1 1A7GT (DK32,X14)
battery operated radio.
3 1B3GT (DY30,U41)
IIRC, the high voltage rectifier out of many b&w tvs...
1 41 (???)
old, possibly audio power. 5 or 6 pin base, might be confusing it with
a #42
1 5-30 (???)
1 5R01 (???)
Don't know
1 5R4GYA (???)
3 5U4G (5Z10,GZ31,U52)
1 5U4GA/B (H52)
Power rectifiers, common cathode, two plates, half wave rectifier.
1 6AG7 (6L10, OSW2192, OWS2601)
pentode, video amp.
1 6AQ5 (6L31, BPM04, EL90, N727)
audio power output pentode
1 6B8H (???)
???
2 6BA6 (6F31, EF93, PM04, W727)
IF amplifier
1 6BL7 (???)
1 6BQ6 (???)
don't quite remember
2 6F6G (KT63)
magic eye tube, used as indicator.
1 6CU6 (???)
1 6J5 (L63,L63B,OSW3112)
dual triode
1 6K7 (EF39,OM6, PF9, W147, W61, W63)
1 6K8 (6C31)
metal tubes, used in older radios/tvs
4 6L6 (EL37)
audio power output
1 6N7GT/G (???)
triode, I think, metal
1 6Q7 (DH63)
1 6R17 (???)
1 6SH7 (???)
not sure
9 6SN7 (???)
dual triode, octal
3 6SQ7 (OSW3105)
don't quite remember
1 6W4GT (???)
1 6Z4 (6BX4)
rectifiers
1 7F7 (???)
"loctal" tube, good for HF use (at that time), possibly tv tuners
1 9A4 (???)
1 9AX (6Q7?)
not sure
2 OC3 (G105/1D,KD24,QS1206)
1 OD3 (???)
voltage regulators 105 and 150 volts, good for about 30 ma, max,
parallel regulators.
That's the best I remember.
