[Amps] FL2OOOB

[Peter Frenning [OZ1PIF]]

That is a feature of this amp, it is old enough to be meant to be driven 
from transceivers with tube finals, that had to be tuned anyway, the drive 
impedance for two 572b's in parallel is about 100Ohm.

On my homepage you'll find a description of a complete rebuild of this amp, 
but the section on the input circuit is equally applicaple to yours with no 
other changes. Good luck.
