A custom made one getting built soon.
A pair of either 310A or 310B or 328A will be the drivers.

Well then, I'll just go and stand in your line...

Dogs & Cats are overrated. If I had 2359glenn-like skills, I'd have a basement 

full of glass and iron.

What might these be?  I can't say I've seen such a plate color before, and the style looks Brimar/Mullard.

 

[sunseeker888]

Don't know about the seller's testing method, but those are relatively early meaning they can take more than 450 on the plate. I've seen later G.E.s which cannot handle ~500vdc anode volts without some plate 'blushing' which of course can release elemental deposits in the anode, thus ruining the vacuum.

They actually look like 6SL7 22mm type plates, not ECC32 or 6SN7.

 

[Xcalibur255]

6SL7 would be logical, I didn't think of that.

 

[rosgr63]

I have a few 6SL7's with exactly the same plates.
The seller was thinking about ECC35 and 6SL7.
 
BTW I tried the RFT 6H8C 1954 vintage with the wide plates and it sounded very nice with my Glenn OTL.

 

[dminches]

Stavros, which headphones have you been using with Glenn's OTL?

 

[rosgr63]

I mostly use my Grado SR325is and occasionally, Maestro GMP400 or DT880.
 
The Grado easily reveal noisy tubes.

 

[Xcalibur255]

Are your DT880's the 600ohm version Stavros?  I've been wondering how great the GR amps sound when used with the types of headphones they are best suited for.

What should one do if a tube is arcing during warm-up?
