Sony tc 377 cooling fan
 
Hello all. My TC377 reel to reel drive motor has a broken cooling fan that cannot be repaired. Does anyone know of a fix I.e.a computer cooling fan 12v, 24v etc. or have a drive motor that is broken and would sell the fan?
If anyone knows the voltages around the internals boards so I could fit a computer fan mentioned above at the right voltage, these computer fans are near silent so I feel would be fine.any thoughts cheers chris

Looking at the schematic the Power Supply Circuit Board produces a nominal 24 volts with 23V and 25V outputs.
