Spectron Musician trun on noise / tweeter hiss

My Musician III SE MK2 with the vcap / bybee upgrades was just delivered and after setting it up and hitting the power switch a cracking static was momentarily heard from my speakers. The same was true when the power is turned off.

I realize that most amps generate an audible hiss that can be heard when you put your ear near the speakers tweeter, but the Spectron seems louder than most.

Do other owners share the same experience??

My MK2 is dead quiet even with my ear up to the speaker's tweeter and midrange.

Besides what has already been mentioned the amp likes clean power. It wouldn't be bad to use a good power cord connected to a condtioner like the Shunaya which allows unrestricted power delivery and diverts the noise at higher frequencies to neutral. Conditioners based on serial/baum device conditioners will restrict power to the unit so I wouldn't use one of these.

Do you have a dedicated 20 amp line for the amp? That migt help also.
