Good Morning Michael,

Well following the oscillator circuit I have found ether broken/corrosive ic socket terminals, so If I can get an other board eg 067.235 then I will remove all IC Sockets and clean the board, and put new ic sockets back in..

Fault shows its self is capstan runs all the time at one speak, pressing any speed changes the light but not the speed of the capstan, and TP1 is 1.2v, and R32 has no effect on TP1...

I have the circuit diagram, but no component layout.

All the best from Alan
