AMI I Hum problem

Hello everyone, I have an Ami model I 200 with keyboard selection (1958) that works completely, but whenever it's playing a record (which is most of the time) it emits a hum! I have this juke from 3 years and it's the very first time this problem appears. I changed the power supply , all the amplifier's tubes without results. Any Ideas?
Thank you very much!!!!
Federico

Hello Federico,

Hum in tube amps will be caused by wake filter-capacitors in many cases. People often change the tubes, but this doesnt´t cure the problems. I think, the amp needs professionell service!





Gruss
Helmut
