Default Re: JVC 3320 Transport Failure

The pulse from the control head looks good and the signal from the drum sensor on pin 28 of AN318 also looks good apart from being 22.8 Hz instead of 25 Hz.The two monostables Det 1 and Det 2 look to have good output signals and the DET Flip Flop has a nice regular square wave output but things start to look irregular at the output of the MM monostable that is fed from the square wave.
