Amplifier Discussion / Ibanez TSA30 - buzzing
November 10, 2019, 12:05:20 PM
Hi all, my first post!

Recently I bought a used TSA30 combo, for the money it was a bargain (180€), me thinks.
Everything works fine except, amp randomly buzzes  when a cable is connected to TS/boost jack.
Twisting the cord can make it disappear and when it has been powered hour or so it rarely makes any noise.
Same buzz can be heard when touching simultaneous plugs sleeve and chassis.
Now this makes me think that signal ground and chassis is connected thru condenser and that should be replaced.
What do you think? And where would this component reside?

Let me make this one clear: It's not a bad cable issue. I tried it with several TRS cables and all those behaved as antenna. The footswitch  itself is not original but does it job perfectly, leds and all.

Thanks
