The Battered Marshall Player Checklist v1.0

[Jack Luminous]

Hey Dan, very suddenly blew two consecutive fuses in my 6505. Was warming up in standby and when I put it gear it crackled and blew. Change it and it did it again. Any ideas come to mind?
I’m having major issues here with rust and oxidation, on everything and since you also live in the PNW you might be having similar issues?

Could be a bad power tube. Could be a bad rectifier diode bridge in the power supply. I had both cases happen on two amps recently.

I'd do first a visual check on the diode bridge. If it look alright then put in some new power tubes.
