Hmm, I haven't seen a Svetlana with copper grid supports. I'll have to pull out my Chathams to check, but that looks authentic to me from first glance. What is causing you guys to say it's Russian knock-off?

I just thought the plates looked similar, the top shield is not distinguishable and I cannot see the getter holders. Busy day for me so I did not have a Svetlana in front of me to compare.

Hello all, a question if I may please.

What is the difference between a GEC 6080 cv5008, and one being cv2984

Thanks

A 6080 and CV2984 are the same (the CV is a military designation, much like the JAN designation for US-made tubes). The CV5008 is identical to a 6080WA which is a ruggedized version of the 6080 (but is electrically pretty much the same).

A great answer!
Personally I just try to use Class A amps as cat butt warmers, 6080 equivalents of course.

Finnegan permits this? I'm in shock!

@JKDJedi - as promised - my Sylvania Gold Brand 6080s came in. Interesting as they have the same date/factory codes. But one of course is a dual mica, one is a triple mica, both with double halo top getters. The base bottoms differ as well, with a black and the other a gray base. Hopefully they will sound good. Will light these up soon.

love it, interested in the grey based (right) tube, might have to send that one to me for further evaluation. , anxious to hear if they both have the same sound signature.

Is that a socket saver for your 6sn7? Or just a design choice for the theme of the build?
Also, I am running the same 100% Russian tube combo (Melz & Svetlana power tube) and loving it.

I am just using a socket saver since I am more apt to change a driver tube frequently. I love the 63 Melz with a Tung Sol 5998, but the Svetlana is a very good tube IMHO. I should put you on the list to hear a 58 Melz that is pretty rare, it will be going to Georgia anyway before it heads to Jedi in California. If I can locate a bunch I will part with some but I am not there yet.

1958 was an awesome year for at least 2 reasons now. LOL!!

The fact that they have the same date code is quite interesting. "GK" in the Sylvania dating scheme corresponds to October, 1960. I suspect that is likely that these are simply cosmetic changes, but since you have both you can verify.

And maybe on it's way from Georgia to California, it could make a brief stop in Ohio?

or could just go straight to California.

It's in the box ready to ship but hasn't been labeled yet. I could might possibly be persuaded to mis-label it for the right offer. LOL!!!

I appreciate your caution. It is certainly possible that it could get lost at my place and never make it to California. lol

By the time it reaches California I hope it is still a vacuum tube. Hard telling what music Cowen tortured it with. Maybe once it returns to Indiana I can send it on to Ohio. It should be heading to Texas soon if @bcowen follows instructions, he is not cheap but he can be bought.
