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?
