X250 DC Offset & Bias Question
I have just purchased a pre-owned Pass Labs X250. Superb amplifier.
I would like to be able to check/adjust the DC Offset and the Bias... The front panel meter is at the 1-00pm position under no signal conditions. The heatsinks are at 39C in an ambient of 20C. LH one is 2C hotter....
Under normal listening conditions the meter is peaking around 80% to 90% of FSD. When I wind it up, the meter is 100%+++ FSD:eek:
It's driving a pair of Apogee Duetta Signature full range ribbons.
Does anyone have any info on setting the DC Offset and the Bias?? Is there any meter calibration too??
Thanks for any help...
Or one the siblings should answer, or a possible owner of said unit with experience in these matters.
Sand on fire, Elwood
