Trying to determine root cause stalled after the owner did not return the power supply. So even if the OP fell ill, seems as though the owner could still return the SMPS for diagnosis. Since the OP was able to resume testing after the SMPS was replaced, appears the rest of the amp was fine.
In support of Buckeye and his products I would only like to make a short observation.
Buckeye is a very active member of this community and has been almost from it's beginning.
Many amps have been sold to our members and others tested by Amir with little to no complaints being made as to their reliability or customer service. Whatever the cause of the failure of this particular amp while being measured, I don't believe we can read anything into
results. Schitt happens and as long as it doesn't happen on a constant basis, looks to me as all is good at Buckeye.
If I was looking to replace the aging amplifiers in my current rig, Buckeye would be at the top of the list.
JMHO
