A common flaw with early era JCM2000's (roughly 1998-2003) was a failing power board. These boards would draw too much current, overheat and then melt the board often causing severe damage to the rest of the amp. Marshall released revised power amp boards to rectify this issue. This JCM200 TSL100 has been upgraded to include the new board and keep this amp from failing due to the faulty design.
