I have a Marshall DSL 100 watt head circa 98' original owner. OVer the past few years
I have had bad luck with tubes/sockets etc. I have found out that the output board(part #201 I think)
was made too thin until around 2003/2004 which causes the board after a period of time to
just shoot voltage every which way. SOme have said this is more common with a TSL. I have even had tube melt---yes melt onto the board. I have ordered a new board and was wondering how difficult this is to install.(i can do minor sodering). And, If I still need to have the amped rebiased even with matched tube sets?

Try contacting Marshall or a factory authorized service center. I know there was an issue with some TSL circuit boards that caused the bias to skyrocket and melt tubes. Not sure about DSL's. I was a tech at a repair shop a while back and remember replacing PCB's under warranty.

Clean the unit out with compressed air. Take pics with good lighting and check the exposures before you even think about taking it apart. You want a very good visual reference.
