What do you think about the 6AS7GT tubes in this amp? Look to be output tubes and i’m wondering if they will work like 6080s or possibly 6BX7S.

This is what the Radiomuseum says:

Power/Output
Identical to 6AS7GT = 6SA7GT
Base Octal
Filament Vf 6.3 Volts / If 2.5 Ampere / Indirect / Parallel, (AC/DC)
Description Note: no 6AS7GT was ever registered. The 6AS7G was registered in January 1946 and the first tubular envelope variant, the 6AS7GA, was registered in 1955.
Almost certainly this tube was created due to a mistyping, 6AS7GT instead of the well known converter 6SA7GT.

Level up!!!!

What is the top wired for, Deyan?

What the hell? These look like nuclear reactors.

Ha ....indeed they do!

The real question is, what kind of adapter do I need to run them in the GOTL?

If one arcs on startup, it might kill me, hmm...

Craziness Wonder what voltage that tube runs at.
And how long are the parts in that hot chassis going to last.

Quite a headphone amp.

Cool. Wondering if it's also compatible in this amp. Seems to be almost the same as the 6AS7GAs.

I think the Radiomuseum text means that there is no such tube as a 6AS7GT. It is a typo. It appears that the 6AS7G and 6AS7GA are the only versions out there.

Note the positions of S and A. 6AS7 and 6SA7 are very different tubes. That is, a 6SA7GT is a "pentagrid converter" which is very different than a 6AS7G.

Those crazy Italians just love adding "GT" to everything.

Holy, my dyslexia must of been kicking hard today, lol! Thanks for catching that.
