Actually, Tungsol 6V6’s are beefier than typical 6V6’s, too, and NOS
ones test hot (read: about 15-20% over average), and are supposed
to sound good, too. But hard to find (so sorry).
Look on the base of the tube to see the EIA code. If you see
“322”, that’s Tungsol, often they turn up under OEM names
like Motorola, etc.

Yup. IMA that trying to extrapolate ratings meant for TV sets to
guitar amplifiers is tricky, bear in mind that, for example, in the
case of 6EY6, the ratings are given as a vertical amp TV tube,
and are chosen to give acceptable life in that type of service.
Indeed 6V6’s were given vertical-amp ratings, and were *derated*
to 10 watts from 14 when used in that fashion.

(gratuitous plug) Those NOS British 6V6-GT’s we sell for
Deluxes for $29.95/pair work swell too.

Our next experiment will be to try some 6F6-GT or 6F6-G
tubes in a Deluxe. Those are pentodes, not beam-tetrodes,
and might yield some interesting results…
