Well I finally got round to this deck again today... after a few hours' work I think I have found the problem.
I first dismantled the motor-clutch mounting assembly and to my surprise found NO sprung /felt clutch there - the motor is directly geared to the spools and its speed is reduced in play and increased accordingly in ff-rew. so there was no mechanical problem there.
Next I changed the capacitors in the power supply just to be sure. No change.
Finally I had a good look at the spool tables, noted that the supply spool has a spring loaded felt pad to apply backtension - THIS was the problem, as it was possible in play mode to spin the spool freely- there happened to be NO backension!. After adjusting the black tensioner screw just above, all was OK.
The only remaining irritation with this deck is that the braking solenoid operates about a second too late. So, for example, if you are in fast forward and stop is pressed, there is tape spillage due to the delay in the activation of that solenoid. Have lubricated it but to no avail....I'm now thinking this is an electronic issue. Any thoughts appreciated!
