Hi there,
My crack has a buzz and I think I've located the source to be a shoddy connection in the entry module. I tried to replace the power cord but to no avail. Is there a replacement I can pick up and swap in?

Can you tell us how you've come to that conclusion?

The power cord is a very standard IEC power cable.

The buzzing started after I bumped the power cord on my desk. I unplugged it and checked all resistances, then plugged it back in and checked all voltages, they were surprisingly reading what they should. If I adjust the position of the cord in socket the buzzing will stop.

It sounds like you might have a loose wire or poor solder joint around the IEC power entry module (or even elsewhere in the amp that's getting moved when the power cord is moved).
I have never seen a bad IEC power entry module short of one being very badly melted.

Thank you. I lightly wiggled one of the connections to the entry module and it was bad despite looking fine. I feel silly but I appreciate the help!
