You're going to have a bit of trouble with the older tubes. They had long
skinny leads leading down to those high-capacitance octal bases.

Hams were able to get things going up around 140Mc/s, but it was mainly
super-regen receivers.

If you want to try it, I'd find the smallest dual-triodes of that era, say
6SN7's, and make up at least one maybe two cascode Rf amplifier stages, then
another triode mixer, then maybe another cascode first IF amp. By then you
should have enough signal to start using old pentodes as IF amplifiers. If
localts are allowed, the 7F7 IIRC is probably a much lower capacitance
dual-triode.

I do recall one post-war Sparton FM set that used a 6AC7 as the RF
amplifier, a 7Q7 (loctal 6SA7) as the osc/mixer, then three 6SJ7's for IF
amplifiers and limiters. Worked surprisingly well.
