6505MH no sound?

Post by xatarine » Thu Oct 06, 2022 10:07 pm

Hello,

New to the forum and first post!

I have a 6505MH that I am not getting sound out of when I plug the guitar into the "input" jack. However, when I plug the guitar into the "effects return" I get a clean signal out of the speaker. Both the TSI LEDs are green so there doesn't appear to be a tube issue.

Thoughts? Suggestions?
Thanks

Make sure the speaker defeat switch on the back isn't engaged and all the gain knobs are up--just in case.

Does it happen on both channels? You might have a bad V1 preamp tube.
