Parts, Service, Maintenance & Repairs / Re: Wurlitzer 140B

Hi, all I'm new to this site  and i know this thread is a bit old,  but i have a 140B that came in for repair, has a loud hum sound that will increase with volume control.  i can hear the keys as well,   if i unplug the pickup  (RCA cable) the hum go's away and the amp is quiet as a mouse.   i plugged in a  MP3 player  and the sound is clean.    some kind of pickup problem ?

let me know what you think Also    i changed out all the caps already  but nothing else.
