Went to play the old '71 JMP50 today and after letting her warm up for a minute, I threw the Standby switch to ON and she produced a loud hum for about 5 seconds, then the hum faded away. After that, she played fine, no humming. The filter caps are the original DALY 50x50 from 1971, making them 44 years old. They look fine, no bulging or leaking, but looks can be deceiving.
I'm going to go ahead and replace them, what are the best choices currently available? I know F&T are well respected. What about ARS? I've heard Marshall uses them in some of their Handwired series.
