Hi,
there is a slight hum with my Baldwin Professional amp so i thought that i'd try replacing the filter caps in the power supply. I used new high quality USA made separates rated at 200V since i couldn't find the old multicaps with the correct values. my problem is that it still hums, and after its been on awhile, the 39 ohm resistor burns up!!!! any ideas? someone please help me as i can't figure this out! (the original caps are rated at only 50V)
i re-hooked up the old caps, and installed a 39ohm resistor and the hum is still there but the resistor doesn't burn up!??? i can't for the life of me figure out why the new caps would cause the resistor to smoke as they are brand new and made by cornell dubilier and spragues. The new caps' values are: 2000uf@200V, 470uf@450V, and four 470uf@ 200V.
any help would be greatly appreciated.............
