Re: Sound Sales PX4 Amplifier
Thanks everyone,
Yes, that large cathode resisitor for the output valves should be 470R and not 47R. (Just another case of misreading the decimal point- will I never learn?) I will add an amended schematic diagram. Will take another look at voltages and see what I can do. Is it safe to keep the output valves as they are and run the amp even if one is starting to fail?
Alan.
