Actually, though, unfamiliar with such a tube. Is it a tuning eye?
I guess not. That would have been the 6F6, I suppose.


Tuning, yes. Eye, no. 7F8 is a loctal VHF twin triode normally used
for oscillator/mixers in new designs between about 1946 and 1950.

It's too bad the RMA didn't give some sort of clue in the tube numbers
for eye tubes. A letter "I" would have done the job.

The Mighty SX-62 uses NO 6F6s. 6F6s are for plebeian S-20Rs and S-40s.
The SX-62 uses 6V6s in PUSH PULL.
