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 (???)
1 1A7GT (DK32,X14)

3 1B3GT (DY30,U41)

1 41 (???)

1 5-30 (???)
1 5R01 (???)
1 5R4GYA (???)
3 5U4G (5Z10,GZ31,U52)
1 5U4GA/B (H52)

1 6AG7 (6L10, OSW2192, OWS2601)
1 6AQ5 (6L31, BPM04, EL90, N727)

===== ===== ===================
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.

I see Harvey already made a pretty good reply to your questions. I
might add that if that wasn't enough, you will probably get lots more good
info on the newsgroup: rec.radio.amateur.boatanchors
