You were dialing the unit up in an effort to reform the electrolytic
capacitors, and if you didn't know that before now you do (look up the
term).
The problem is, this may be catastrophically wrong with modern gear with
swtiching power supplies. Old tube gear could very often be brought back to
like like this. But, switching supplies are constant power devices, and if
they start up at exceedingly low voltage, they will draw excessive current.
So, one may have to reform capacitors out of circuit on such gear.
