Vintage Webcor Amp


Recommended Posts

hey guys i just stubled upon my great uncles old webcor record player, its like a suit case with two speakers that swing out from the sides and have speaker jacks on them, i pluged the speakers into my lil gaint and they sound awsome , my question is on futher tinkering with the rocord player i noticed thats its loaded with tubes, it says 70 watts on the back this thing is oldddd, but is there any way i can turn this thing into a guitar amp head?

Anything can be turned into a guitar amp, if you have the patience, the know-how, and the desire to do so. The question would be "is it worth it?" That's hard to say, without seeing the iron, the tube alottment, the layout of the chassis, etc.

 

I recently saw an absolutely gorgeous vintage PA amp that was military (navy). The thing was a stunning work of art, inside and out. Absolutely beautiful. The iron was impressive, the wiring was flat out amazing, and the entire amp was pristine. I ALMOST bought it, but then took a good hard look at the chassis and realized that it would make absolutely no sense as a guitar amp.

 

I seriously doubt that device is 70 watts. That may be the power consumption, but I seriously doubt it would be the output rating. The fact is, it may well be that the speakers are the only parts of that thing that have any value. If they're old Jensen alnicos and they're in good shape, you could probably get a few hundred dollars for each.

This is more than likley true. Best way to tell power output would be find the output tubes and note type and how many there are. This would give you an idea, at least. Types of tubes used and count would be a good factor in determining wether or not it is a candidate.

well im not shure thats just one of the things I can barley read about it but it has two 12AX7's two 6BQ5's and one 5Y3 so im not shure what that puts the power at but thats what the tube guide says thats on the inside of it, and it actually looks wired pretty well the only thing that i found is that i would have to change the circut for guitar instead of spinn wax

Ok I know I'm not crazy, what happened to the other replies to this thread, there were some good links to building tube amps and now they're history.

 

Was it a no no for those people to post those links? If so, if you posted those links please PM them to me if possible.

 

I spent all night reading and researching building tube amps last night but I didn't save the links because they were here banghead.gif

 

I wish I could stumble onto one of those record players, that sounds like an awesome start for an amp project

 

Also about the tube rectifier, a rectifier circuit converts your ac wall current to DC current, that record player does it by means of a tube circuit instead of silicon diodes or bridge rectifier.

 

Purists will tell you a tube rectifier is the only way to go, but opinions do differ on the subject.

 

Regardless, what you have is a KOOL start

but do you think someone with pretty good knowlege and experince with electronics could turn that into a guitar amp head?

Maybe. If not, you should be able to find an amp tech somewhere nearby that would do it for you. Electricians aren't generally going to know anything about tube amps and very little about electronics. Their working knowledge of circuits is running wires from a fuse box to a switch or outlet.

 

FWIW, amps with tube rectifiers will sag or compress much more when pushed hard than a similar amp with SS rectifier. This is entirely personal preference, and the only way you'd ever know what you preferred would be to log some miles on both.

 

There are numerous sites online where you can find resources for this type of project.

+1 i never saw the links either and guess what else i found in the storage unit as well to turn into an amp, an old webcor reel to reel that has a tube amp inside of it ........................................................................................... ive got two new amps if i can get the right people to do it

an old webcor reel to reel that has a tube amp inside of it

You're probably better off just selling that. The only part of it that would really relate to a guitar amp would be that it has a preamp. It's very doubtful that it would have the primary iron to handle output tubes.

 

The other thing is totally worthy of an amp build, as long as the iron and chassis aren't all corroded, and as long as that primary iron is working properly.

+ to that, in my reading frenzy the other night it was mentioned how the Reel to Reel amps weren't too hot for guitar amps, a lot of useless circuitry to remove, the record player however is another story!

 

If you decide to give up on the idea let me know devil.gif

 

The big neighborhood garage sale is tomorrow and I intend to scrounge for a donor.........
