Amplifier Issues (Avenger 50W)
Post by admakeitworthit on Jun 15th, 2017, 11:18pm

Hi All,

Just reaching out. I have had some issues with my Soldano Avenger. When the amp is turned on I am getting a crackling and popping sound. This is occuring with both the Preamp and the Master on 0. I have troubleshooted with different leads, power points, guitars, speaker cabinets and even speakers to no avail and it is getting more and more constant. I have also installed a brand new, matched set of Sovtek 5881/6L6GC tubes replacing JJ's that my amp tech installed last service. It is rebiased to 28ma.

Any ideas what this could be? I am worried that I have caused the issue.

Thank you so much.

Kindest regards,

Do you happen to have a schematic for your amp that you could send to me to look at ?
I only have the schem for the SLO and I'm not sure how comparable they are...

Preamp tube?
