With the clear glass, there is also a black-plate and a grey-plate Tung-Sol 6SU7GTY.

Thanks Rob, I only have the three types, so here is the new list:
 
 
Tung-Sol 6SU7GTY update.
 
They come in four flavours:
Black Glass Round Plates, parallelogram mica.
Black Glass Round Plates, round mica.
Clear Glass Black Flat Plates, triple mica.
Clear Glass Grey Flat Plates, triple mica.

I actually have a couple pairs of Sylvania 6SU7GTY, which are clearly Sylvania internals. I'm assuming they are just a 6SL7GT with a brown michanol base, but they are a rare bird.

I have a Tung-Sol BGRP 6SL7 with grey plates which I thought was interesting.

I will have to go through my stash of 6SL7/6SU7s and see what I have.

Rob, are those 6188s?

The Sylvanias? No, they say 6SU7GTY. I do have some Philips 6188's too. They are pretty decent tubes as well. And actually you can still get those NOS JAN-6188 from Parts Express.

 

[dminches]

These say both 6188 and 6SU7GTY.

 

[Skylab]

Yes they sure do! I will have to look at mine again but I'm not sure mine have the green JAN print.

Hello,
 
OT here but just want to ask if anybody have a lead for a pair of type 26/UX226 tubes?  Preferrably "globe" type.
 
I posted this here as I figure that enthusiast who collects 6SN7 tubes might know some leads for buying the type of tube I am inquiring.
 
regards,
 
Abe

Hi
 
Would these be Bad Boys?
 

 
The seller claims they are a matched pair but the plates look slightly different and the date Dec 1959 seems way after the 1952-53 Bad Boy period. They look like 3 hole black plates with copper rods though.
 
Thanks

The left looks like a Sylvania and the right like a Hytron.
 
It could be old stock rebranded in 1959, the left one does look like a genuine Bad Boy.
 
BTW the seller is good, and gives a 14 day money back option.
He tends to call most his Sylvanias Bad Boys, even if they are not.

Somehow I don't get the Hytron vibes...
