I have been getting e-mail from folks addressed to " mail list amplifiers" .!!!! anyone know where this "list" comes from???? The msgs are not a problem in themselves, but they appear to be like what I'd expect from "amps at contesting. com !!!!!!
Also , while I'm here , I'm going to strip my old HB amp.
4 811A's .etc. The important parts of course are the transformer, from an AL811H., the tune and load caps.
the tune cap is was a "kit" from ten-tec. modified to give me two sections , one about 35 pf or so for 15-10 mtrs. input coils tuned for the 4 tubes mentioned.The meters are 1 ma. movements, size I'll have to go measure, but with hand made faces for the ckts . grid mtr. 300ma. , plate mtr 1 amp, plus HV scale 2000 vdc. a smaller mtr. for rel. output., all switches for pwr, etc. The filter caps. are 10 ea. 100 mfds. 450 volts , series /par. axial leads, on their own vertical boards. If any interest , please e-mail me off list.
thanks to all.!!!!!
