Loud Sqeeel When Turning Amp Off

[89custom]

The 59 Marshall Splawn that I accuried occasionally make a high pitch squeel when turning the Mains off. Sometimes it clicks pretty loud when turning the standby off. Of course I turn the standby off first.....any thoughts.

It's a badly designed modification to the amp that's causing the problems.
