Re: Mayfair FT-305 Small Reel to Reel Check Out
9V battery supply (-ve) being switched though to the PCB when Play (Forward) is selected.
0V (battery +ve) permanently connected to the PCB, this also somehow connects to chassis/ground.
Visual inspection of PCB shows nothing untoward.
Trying to work out the PB/Record Head wiring through the Play/Record switch to the PCB, also the loudspeaker wiring via earphone socket. Tried connecting earphone, still no sound on playback.
Erase of existing recording (by selecting record) works fine when tape played back on another machine but this is just due to the tiny erase magnet.
