Just got this amp and I don't know it's history. On the clean channel with the gain up around 70% or greater there is a crackle. It may be there on the lead channel as well but being masked by all the gain. Seems to be worst when using my bridge pickup. Things I've already tried:
New power tubes, swapped the old ones just to make sure I didn't get a bad new tube
Used a known good 12ax7 and swapped in all positions
Tried a different speaker
Different guitar
Different cable
I used the amp at rehearsal last night and didn't notice any problems but I was playing fairly clean with not much volume. Here is a clip where during the first 30 seconds I striking the low E string then without playing I turn up the master volume very loud. Thats where you can hear crackle.

Hope someone has an idea for me.
