Old B&W TV tubes useful for audio?

for TRULY GREAT MUSIC
Couple of weeks ago we were in town to pick up an empty console from another AKer. My wife's aunt heard about it and asked if I'd want an old 'stereo cabinet' that's in her garage that her husband was going to make a bar out of it but never did.

I've been in her garage quite few times and never noticed any console there, but there is a lot of stuff, so maybe I over looked it. In any case, we've got the back of the Jeep filled with the other one, so we'll look at it next time... he died over 25 yrs ago, so it'll keep for another few weeks.

Since then, I've been thinking about what this thing might be. They always bought higher-end stuff and I know there's a nice Magnavox console in the living room that she still uses for the radio. I'm seeing Fishers, Scotts, maybe Grundig (they're German).

This week we were back in town and she asks me to come see why her tv isn't working right... she's been confused ever since we had to put the DTV box on it. After straightening that out, I nonchalantly walk into the garage. I don't see anything that looks big enough. She says it's in the middle of the floor under some black plastic and boxes. I start removing stuff off the only pile in the middle and I can see something wooden at the bottom but it doesn't look big enough to be a console.

Eventually I uncover a walnut case about 48" long by 30" wide but only 12" thick laying flat on the floor with the masonite back facing up. I'm thinking an upright radio, but when I start reading the back I realize it's a TV! Awfully thin for a tv I think.

So I stand it up on it's end, as one of the legs looks a little weak. It's a B&W GE TV in a really sharp '60s looking cabinet in very good shape. I'm impressed by how thin and narrow the whole thing is, but I have no use for this... unless it's got tubes?

There are at least a dozen hex screws holding the back on and only a pair of pliers to remove them. It's 95 deg in the garage and I'm already soaked so I might as well keep going. I' finally get the back off and see that the narrow end of the picture tube is dangling... broken off. But it does have tubes, and a lot of them!

The model # is unreadable but there is a tube diagram.
Here's a list of the tubes:
6EA8
6ES8
6AF4
6AQ5/A
6BY6
6DN7
6CG7
6AX4GTA/B
6DQ6B

6BQ5
6T8/A
6AV6A
6BZ6 (2)
6CB6/A
6AW8A
1J3

The few tubes I can see easily are GE and at least one of the larger ones is an RCA. I spent the evening googling and so far only find the 6BQ5 of some audio use... apparently an EL84 sub?

I have no use for the tubes or the TV, but before she throws it out, I thought I'd check here to see if anyone knows if there's any use for these, audiowise.

The 6BQ5 is indeed the same as EL84. The 6AQ5 is similar, a bit lower in power. The 6EA8 and 6AW8 and 6T8 were popular tubes in lots of gear, especially Heathkit. 6DQ6 is a powerful tube, used in some ham transmitters, capable of maybe 50 W RF output.

6BZ6 and 6CB6 used in some FM tuners. The 1J3 is a high voltage rectifier, of no particular use today.

Don't throw out the tubes; someone may want them.
 
Thanks.

Here's the same list with some of the notes listed on the tube layout card.

That TV may have a useable picture tube, someone on the other forum
(videokarma.org) might be interested. Those tubes are no longer being made
or rebuilt, so any good one should be saved. Regards.

P.S.: sorry I had missed the part about the broken picture tube. Could still
be of interest for some rare chassis parts. Good luck with your projects!

Our camera was acting up while we were there, so I didn't get a pic. Any clue where to find a catalog or list of 60s GE TVs? I spent hours looking the other night but only found older sets.

BTW we couldn't bring it home with us right away... we had the car this time, not the Jeep.

Someone could surely use the tubes. The 6CG7 is a nice dual triode, very similar to a
6SN7. The 6AQ5 can be used for a decent sounding output tube. The amp in my avatar uses 2 6AQ5's in each channel. In push pull configuration they are good for 10 watts.
