How to Spot a NOS 6V6GT Vacuum Tube

[23zoid]

Are these NOS or just OS ?

Very informative. I use a lot of 6V6's....I have 9 Ampex portable speakers that use them.

@MyLesPaulcopy Hi, check out our stock list on our website!

You forgot to mention the 7408. Same as a 6V6GT in every way, just an alternative label.

I have just come across some old 6V6's. Some Sylvania's, a RCA gray glass, a Hammond clear glass, (which I think was made by RCA because of the code "274" on it) and a CBS.

I can not find out anything about the CBS. There is no manufacturer code. Did CBS make their own tubes? It has what I think is a date code of 5748, which I think means the 48th week of 1957, correct?

Thanks for the informative video's!

@scottb1966 Yes, CBS did make tubes, the earliest ones were branded 'Hytron'. EIA manufacturer code 210.

Thanks for making this info available.

Please-- get in to your camera menu, turn OFF the autofocus! It's giving me a headache.

[audiotubes]

I should re-shoot this video. I no longer have this camera and the focus was really a problem in this video. Thanks for watching!

@audiotubes when you reshoot, don't forget to add the GE version and point out the russian and chinese fakes too :) otherwise, very good series on NOS tube spotting.

[audiotubes]

@MovieTech Thanks!

It's worth noting that pin #1 of the metal 6V6 is tied to the shell, so it should not be plugged into an amp that uses pin #1 as a tie point for the grid-stopper resistor. Same deal for the metal 6L6's.

[audiotubes]

Absolutely correct. That is why the metal tubes never caught on for guitar amps. If your amp does not have a connection for pin 1, or it is just ground, then you can try them. They are much less costly than the glass versions.

Hi, great video. Aren't you supposed to avoid touching the glass portion of the tube since fingerprint oil heats up when the tube is on or whatnot? Do you sell 6C10? Do you have 1982-86 Fender 6V6s for Super Champs? Thanks

[audiotubes]

The tubes don't run hot enough to have a problem with fingerprints. That is mainly a problem with Tungsten-Halogen light bulbs. But any dirt or oil on the glass can get baked on and be hard to remove later. We sell 6V6 and 6C10 tubes for all Fender and other amps.

@1234whatever

That only applies to quartz envelopes, not regular glass as used in vacuum tubes

[jackillac92]

I sell yes? How much is can me sell tobe four? Is tobe grood, o no? Got good money awff tewbe?

[audiotubes]

It probably sounds pretty good, too. Some antique radio sets used the 6V6, but it was more of a hi-fi and guitar amp tube. Thanks for watching.

i've got a 6v6gt gray glass valve in my radio
