I have Sony D5 that...well I bought new....used for about 6 years and dropped in on asphalt one night...
Subsequently I took the motor out and put in in another broken D5...which worked great...
The old one I want to be able to use the preamp...its been sitting awhile...
When I put batteries in the preamp is laden with FM like static...very loud...something is screwed up...
Any ideas...is there some voltage leaking around the board...?
I'm not so sure I didn't once screw up the DC-DC converter...I cant remember.
