[TenTec] Resurrecting Hercules 444 amp

I was given a Hercules 444 amp, and I have it working on 160, 40, 20, and
15. However, on 80 M, the I/V light comes on with any more than 10 watts of
drive. The amp is stable and produces rated power on the other three bands.
Any ideas why there's a difference on 80?

I know TenTec abandoned this amp when the transistors became unavailable,
but mine still works, and I'd like to get some use out of it.

Tnx ex 73 de AL7L
