Best I remember, they were REALLY sensitive on the input. A 3-Watt walkie-talkie would drive the devil out of them on 'High'. Any radio much larger than that would sound better on the 'Low' setting. There was NO such thing as a two-final radio when this thing was new. A large radio back then was around 20 Watts PEP.
If you poof the transistors, they are a pain in the neck to find. The threaded stud-mount package hasn't been used by manufacturers in 20 years. Every so often we would see one that had the nuts underneath the transistors loosened. Somebody thought they should be loosened to remove the cover, and would not tighten then back and key it. Instant POOF.... Substitute transistors always required changing capacitor values and transformer ratios. I'll be surprised if all the relays are still happy. More likely one or the other will start cutting out on either receive or transmit side, or both.
Uh, you said "Worth Fixing" ???? If your labor is free, the parts alone, if you figure relays and RF transistors, will be nearly half what a small amp that swings 120 Watts costs new, these days. Linears have never been cheaper. Fixing an old stud-mount amplifier might be fun, but it won't be very cost-efffective, at least not until new amplifier prices go up by double or more.
