Default Binatone answer machine , model 3900 from 1981

I know its ancient but the owner does not like the new ones that loose
contents on power failure, has standard tapes for messages he can archive,
does not auto rewind to message tape start, 20 minute long messages possible
etc. No message count is the only down side.
I've not repaired one for 15 years or so , so i'm rusty.

It was not responding to anyone dialing in, ie no OGM.
Of course I try it with telco's "line test facility" and it works fine as
far as starting OGM and starting record cycle at end of that, so presumably
an intermittant fault.
The phone lead and plug are fine but
I've not fully taken it apart yet. Other than checking for worn belts,
slippy pulleys, corrosion on manual-change function-switch and change the
cap that charges up analogue fashion after a pot-settable approx number of
rings is there anything else to check. ?
