Saw its rd45 is at 440v too.
Find it is pretty big difference...
Would be great to know the ''standard'' factory plate voltage.
BTW, I asked music corp the max dc bias current the OT can handle, here what they answered : I'm very sorry but those specs are for internal use only and are not available to the public
they just say factory bias is 35 ma, but don't know for what voltage, gonna ask them.
As you mentioned mine does seem a bit high. And yes I asked if you were opether because you both measured at 440. Come to think of it, it seems that most of my amps run a high plate voltage when compared to others. Maybe my probe is bad or my house's voltage is higher. I believe I measured the house not too long ago and it was 119 at that time. I'll have to look into it more or measure with a different method to see if the probe is bad.
Hmmm...35mA almost seems a bit high for a factory to kick out an amp with. But maybe...
EDIT: I just measured the house again really quick before bed and I'm getting between 118.8-119.3V...I'll keep investigating. Nico22, have you measured the voltage from your wall that this amp is plugged into (just curious)?
Jeff Hilligan,
Did you happen to take a reading or play with the bias on this amp by chance? Just trying to get a baseline. Thanks.
No I did not
