I combed the Internet trying to diagnoss the dreaded horrible crackling sound fender HRD amps make. They are notorious for this I have come to find out. Most people take them to an amp repairman because they can't figure out the problem them selves. I have been there/done that already a few years ago. Paid $150 to fix this same problem...and now it rears its ugly head again. Well I tested the power tube and preamp tubes and they were all good and none were micro phonic.
Long story short I couldn't find a component problem.
But I'm not dishing out any more dough to fix this sumbitch so I didn't give up!
I got the main circuit board and the power stage circuit board exposed to the point where I could get a soldering iron to them and reflowed every single solder joint on both boards.
It's like a brand spanking new amp now.
I guess it was a bad solder joint somewhere.
I hope this helps someone else solve the commonplace crackling noise quirk of this line of amplifiers
