As far as I know (I am an authorized Marshall repair center) parts layouts are not published. The boards are silk-screened with part numbers, and in older units the parts are quite easy to identify by where the wires go.

If you are talking about the mid 70's Marshalls, the PCB layout is almost identical to the turret board one. You can easily draw one up to make a transfer.

Doug Hoffman made a version of the 70's marshall and did up this PC board for it:

You could try that.
