Re: Marshall JTM45 Guitar Amplifier- Mains (Primary)Fuse Blows
Players like to drive them into rectifier sag rather a lot, it's why they want thermionic rectifiers in the first place. This puts an awful lot of heat into the bottle, stresses seals, outgasses everything, vaporises metal and generally takes them to the point where you can get an anode-to-anode flashover. Bye bye transformer.
The valves which survive are those which can take excursions right off the datasheet and onto the next desk.
