Marshall vs232 makes a high pitched hum always
Marshall vs232 makes a high pitched hum as soon as i switch it on. If my guitar's plugged in it makes it louder as does when i turn the volume and reverb knobs. I can't even hear my guitar through it

I hava same problem with VS 100, did you find solution?
I saw this symptom last week on a similar amp. It was due to the reverb tank having come lose and being stuck magnetically to the back of the speaker causing wild feedback as you describe. Worth a look before getting out the soldering iron.
Change the audio amplifier ic are fried
