Default 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

Hello Chris and welcome to the Forum.

Service manual which includes the schematic can be downloaded from sites such as elektrotanya.com and hifiengine.com

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