Chuck,

Do want one of those HP counters? I have one.. back in New England.. left 
over from my 1960's scrounging!

Thanks for your comments on the FM modulation in the 606's ...  The 
modulation signal is applied at the RF Amplifier screens.. I wonder if 
better B+ filtering for the oscillator might eliminate or reduce it.

I have two 606''s here, one A in very fine shape a one B needing work and 
intended for use with the 8708 synchronizer.  Both of these will come out 
of retirement once the cellar is overhauled with a new, LONG work bench 
constructed.
