Having a problem with the power board with this unit. Anyone else have a similar issue. Cant find replacement parts or a schematic. tested caps and diodes and mosfet. Look good but it blows the fuse.

These are nice units ! I picked one up like brand new at a local thrift store for $3.99, non-operational condition .. I discovered a simple cold solder joint to be the culprit and I am happy to say that it has been working fine ever since I re-soldered it.
Good luck ! Mark..
