Marantz CP430 fault
I have had the exact same problem with a CP430, Whether in Play Rewind or Fast Forward, after a short duration the tape stops. After a lot of Looking & thinking, I noticed that a few seconds prior to the tape stopping, the tape counter stops. (If you dismantle this unit be sure to work in an orgainsed fashion,& you will need some tiny Phillips head screwdrivers too) If your not confident then dont proceed.
The tape counter is driven by a belt, & on the spindle that drives the counter is a magnetic wheel, that runs past a sensor on a PCB.
I didn't have a replacement belt, so dismantled the unit, & chemically cleaned the Belt (cellulose thinners), until no more 'black' came off, in order to eliminate the possibility of tape slip, I also used a stiff toothbrush, to clean the plastic gears that drive the counter, as any resistance, will cause the belt to slip. I think the reset button had also been pushed hard, & bent the mechanism slightly, as it had a tight spot, so i adjusted the spindle, & finally lunricated the Counter gears (Not the Spindle & pulley, as its too close to the belt to introduce lubricant). Upon reassembly, The problem seems solved, the unit now plays records Rewinds etc, without any issues.
Its a tiny drive belt, & any resistance in the drive train, (dust / fluff / as tiny grit even) is enough to cause the belt to slip, & stop the counter which in turn stops the tape.
I hope this helps.
