Trouble with my Lonestar Classic (Drive Channel Crunch)

[texin976936]

My Classic has no volume loss, or any signs of problems, however my drive channel has lost a lot of crunch....Still has plenty of volume, but not like it should...I have checked preamp tubes and power tubes....

Does anybody know what could cause this? like i said, the amp sounds great otherwise, just dont have as much drive.

Do you mean you re-seated the valves or changed them?

Loss of definition or crunch normally comes form worm tubes. I would swap the preamp tubes controlling CH2 first, then go for the power tubes if you still have concerns. Changing a preamp valve or 2 is certainly a cheaper option if there is still life in the power section

Good luck
