Hi Don,
you have probably mixed GU-84B with GU-74b...
Tube ( s ) in OM-3500 were not GU-74b's...
Have not had such worries...bought a Dentron MLA-2500B,
with original tubes :) When they failed we will switch to 3cx800 :)
Rgds,
Nermin S58DX

Subject: Re: [Amps] GU-74b amp by UX1UX
While attending the Friedrichshafen 'Ham Radio' gathering in June, I
was told that the GU-74b is no longer being manufactured, so is not
available in any large supply for replacement/repair.
For this reason, the OM-Power people have discontinued the OM-3500 amp
and replaced it with another model.
Good luck es 73

Does anybody see any obvious flaws in this amp http://goo.gl/lqPBie
I could not find the actual schematic.
I'm thinking of buying a Ukrainian made amp, for nostalgic reasons :)
