Hi Mark,

good news and bad,

switched the jack you kindly sent me, no problems at all in that respect. however, the problem persists. ie, plug it in and nothing, short the neg of the jack to the chassis and it boots up as it should, hmmm, got an empeg owning pal coming over today so will see if he can spot owt obvious, if not, ill have to coonsider sending the pcb to someone, is that possible?

regards.
Hugh
