I doubt you will find any PCB's new for the B200.
Its possible you could get one second hand, but then it would be as old as
yours.
?
If its just the edge connectors you can get a
special abrasive tipped pen which takes all the crud off of the contacts on the
PCB. its a fiddly job but well worth it.
?
The worst thing you can do..(I know because I did
it once!) is to add new solder to the PCB edge connectors..it doesn't work..in
fact made things worse.
?
If you really love your B200 its possible to clean
the contacts on the PCB sockets too..but its very fiddly and very time
consuming...something your engineer might not want to tackle

hammond or leslie?
i also have a b200 with an 822 leslie and have experenced
the same problem
more than once, espicially after transporting it and
setting it back up and
even though i am not brave enough to try to repair
the problem myself it has
always been the solder joints- like darren said-
sometimes plugging and
unplugging 2 or 3 times will cause it to opperate
and a couple of times i
have even put a little pressure where the leslie
plugs into the hammond and
have repaired it--- to slove the problem of -is
it the organ or is it the
leslie i bought? a pre amp for the leslie
which i thougt was a very smart
purchase-- now i ck to see which one is at
fault--- my tech tells me i
really need a new mother board for my b200 but
he says they are
unavailible--- does anyone know if that is true??? when i
travel most times
i take the b200 -- but when im home-yep you gussed it---
the b3-?? bluesb3

Its hard to say whether its from the organ or

organ its most likely a PCB edge connector. Hammonds

re-fitting can cure it.
