I'm new to electronics and am working to diagnose the problems with a non-operating, Pioneer RT-909 reel to reel tape deck. While there is electronic power to the unit, there is no power to any of the mechanical functions. I've found and replaced some bad capacitors and have spotted a few questionable transistors, but these have not resulted in any changes. The schematics show few voltage specifications, however, they do show that, from the transformer to the reel motor control circuit board, the specified voltages are 125 and 85 vac for each motor. My readings, directly from the transformer are 78 and 38 vac for one motor and 52 and 23 vac for the second.
Based on these readings, is it reasonable to conclude that the transformer is faulty?
Thanks
