Hi bc,
These are 6N7 octal tubes. With a ECC31 to 6SN7 adapter they can be used as 6SN7 tubes.
They are dirt cheap since they have no tube glow or visual appeal, but sound very good.
I recently bought a pair for $5 + $7 shipping (the seller accepted a $5 best offer instead of $10). The tubes are from 1944 and looked like they never were out of the original boxes.

Thanks for that link, Mordy.

Oooohh...I don't have any of those. What is it?

Just a heads-up on these, 6N7 / 6N7G / 6N7GT all have 800mA heaters.
Best to check the amp capability if using 6SN7 @ 600mA.

Is this the adapter I need for the Ken-Rads?

Yes, for MJ2, plus socket savers for extension.

Good catch, at least with the Lyr 2 you need 2 pair of socket savers (four in all) to lift the huge adapters all the way out of the tube pit since the hole is too small. So that's an additional expense but a one-time one.

For some reason the adapters I've ordered sit in customs a lot longer than the 2C51 adapters. Maybe their Frankenstein appearance makes them look more suspicious. They probably have landed me on a no-fly list.

I see Autostart has dropped the eBay price on his Ericsson 2C51s to $97 so I bit. Can't have too many 2C51s, right?

Just to add to this. You do need another pair of socket savers on top of the ones you currently have in the MJ2. I've tried that adapter without the extra socket savers and it didn't work so well, lol.

Luckily I just so happen to have a spare set sitting around just doin nothin.
Here we go again further down the hole that’s now an abyss. Lol

If you happen to like the mids of the Tung Sol 2c51s and want a more larger and holographic sound, do try the 6C8G version of it. It’s a bit expensive but to me they’re worth it. The Ken Rads have the energy for the genres you like and are much cheaper. The TS tubes are more of acoustic and vocals.

No problem bro! We’re all here to help enable our addictions. Thanks @rnros for the link to the adapter.

Those 6c8g Tung sols must be the rarest tubes on the planet because I found I set from India. I’ll just keep looking

6SN7 equivalent tubes. The MJ2 doesn't take them but the original Lyr does.

Edit: And Lyr 3

Edit 2: By the way bro. Have you tried the 6C8G to E88CC adapters? I think you'll like those tubes. Ken-Rads are pretty powerful. This is what I kind of thought the Seimen's CCas were going to sound like. The Tung-Sols are my favorite. Imagine the tiny TS 2c51s but multiplied 4 to 5 times. Bigger in image and holography. Then you have the National Unions which are kind of...boring to me. I haven't tried the Sylvanias, RCAs, GEs, or Marconis.

Ok, need some clarification. Are the Ken Rads the 6c8g? Having a difficult time finding them.

The dude from India is the only one I've seen selling the Tung-Sols in any quantity. He does ship super fast though. 4 days if I recall correctly.

Here is the guy with the Ken-Rads I bought from:

@koover, This is the same one I have used.
Different sellers, couple years ago, but same military batch/box from the Canadian supply depot.
(Has a second label on the box for the source.)
BTW, $15 each is a great price. $75/pair in 2016, and I thought that was a bargain!

That's where I got my Tung Sols. And you're right, I was shocked how quick the delivery was. Beautiful black glass tubes.

Edit: I could have sworn I only paid $60 for the pair and the matched pair on ebay is now showing $120. Maybe I'm deluding myself. Think Tony bought from the same seller...Tony, do you remember how much you paid?

My profile pic is the Ken-Rad 6C8Gs, by the way. Purty.
