Question about Audio Players & Recorders
I have a Realistic (Radio Shack) TR-3000 reel-to-reel deck which I'd like to get fully functional, to sell the unit. I know I can sell the unit "as-is", but I was hoping to get it working first. Transport functions 'Stop' and 'Play' work fine, but 'Fast Forward' and 'Rewind' are inop. Both reel motors seem to be fine- in 'Play' mode, the takeup reel and supply reel motors are both energized and supply approximately the correct amount of hold-back and takeup tension to the tape. But in fast-forward and rewind, neither reel motor is getting current. The reel brakes are correctly disabled, and I can turn the reels easily by hand. My guess is that there is something wrong with the transport logic board for the fast-forward and rewind functions. I don't have a schematic of this exact recorder- but I have a service manual for a similar TEAC deck- the X-3. In fact, I think that TEAC OEM'd the TR-3000 for Radio Shack.. it appears to be the same deck, with minor cosmetic differences. Does anyone have suggestions as to what components on the control PCB or another board in the system might cause fast-forward and rewind to not supply current to the reel motors? Btw I was able to do an electrical alignment (monitor, record, play) on this machine, although it was "interesting" to work with it only having stop, play, and record available.

This could be a head fault? Another possibilty is the preamp stage. You will need to look for something that would take out both channels. Such as an IC.
