Default Re: Philips N4510 reel motor

I have no idea how my friend found the motor, but I asked various people if they had any idea where to get one and he managed it. I think many of us have rare parts in the junk box (I certainly do).

The driver transistors that I am having problems with were originally AC128s. THey are cross-coupled to BC147s (or BC547s) to make flip-flops. One of these flip-flops (and thus the AC128) drives the pinch roller solenoid directly. A 2N3906 (which is what I currently have in there) is not big enough for the job really. I think I can get something that will do though.
