Loud hum from speakers while in phono - what am I doing wrong?

And I must say that some of us, and not mentioning any names, are a bit 'obsessed' with the collecting of stereo gear and
therefore should be avoided.;)
 
If the RCA's are detachable try replacing with different one's. If not, clean the RCA's , cartridge connections and head shell connections with contact cleaner. Make sure that all are firmly connected. Make sure cartridge connections are correct. Keep the turntable as far away from any digital appliances/gear as you can.

I suspect the problem is inside the amp. The rusty connector isn't making contact with the chassis and the 0V line it's supposed to be connected to.

If the problem is with the amp, can I expect that cleaning the rust off will be the fix? Or is this something I’ll have to dig around inside the amp to deal with? I hope not, I’m still a total novice with this stuff.

Will definitely be replacing the RCAs if simply cleaning the rust doesn’t work out.

I'm only guessing that's the problem, but if it is it will require some work internal to the amp. I doubt cleaning rust off the outside will fix it. I could be wrong though.
 
I would BE betting on the RCA'S being the problem. But that being it could be the connectors on the amp not making a good connection do to corrosion, or not making a firm grip with the plugs. Get some tarnish remover and a tooth brush and scrub them RCA'S.
