Why do these tubes look weird to me?

[Jakedog]

This is a purported ‘77 Deluxe Reverb, fully serviced and up for sale or trade, not too far away from me. Decent price I think. I realize it’s hard to tell much from this pic, but I’ve never seen 6V6 tubes that look like that. Now that’s not saying a lot, I’m definitely no expert. But they look odd to me.

Raytheon by Zenith.

Right on. Good? Bad? Just different cosmetics?

They look thinner because of the reflections and being black valves.

With that limited view and no markings on the base they appear to be Russian 6P6S. Tough to tell without a closer look. Or ask the seller.

I have a set of 60s era Raytheon 6V6s in my 5E3. They're great, been in there for years and had replaced a set of 60s era Tung Sols. If I'm remembering correctly Zenith primarily sourced from RCA, Sylvania and Raytheon.

They are pre-pubescent...

I bought one branded RCA for pretty cheap, didn't sound any better than the new Tung Sol 6v6GT or the 6V6S from JJ to me so in the box for a spare.

I noticed these type 6V6's start popping up all over when the market got spooked by global events a few years ago.

They look like NOS RCA 6V6 tubes to me. I have them in several amps.

ymmv. bought some of those alleged raytheon/nationals (were russian) for my super champ. redplated immediately (which is hard to tell cuz of that black . . .)

Looks normal to me.

I have a couple of RCAs that look like that...

Black bottle called smoke glass ae common, but the very shiny base and no writing is a bit less common.
I was also thinking the Russian 6p6 as @Powdog suggested.
Old Raytheon are great but the base should be matte, not shiny.

Good, any old tube that still functions is generally better than current. I'm guessing that's the rectifier tube to the leftmost in the pic. looks like the same manufacturer.

They look perfectly normal

Just over the boarder. More than I want to invest in an amp.
