Technics SA GX303

[ept]

Blows main 5 amp power input fuse, F1. Same problem reported by another
person around June 1,2001. Looks difficult to physically get access to any
failed part. I ordered Service Manual and am waiting to receive it. Have not
tried disconnecting at CN604 yet. This was reported in 2001 as stopping the
fuse blowing. Some slight board discoloration in area of Q703,Q704,Q705. Any
help appreciated.

Lots of stuff crammed inside these things so service PA components is
not always easy but not impossible.

The manual should have some tips regarding accessibility for
servicing.
