Well when i got up after thinking long and hard i found this......
A tiny spring was not hooked to anything and i could not see anything to hook it to, but i could see the spring was the tensioner for the Betamax style magnetic tape end sensor ( optical in VHS ) so i fooled the machine into lacing up with no tape in and pushed the magnetic sensor, and hey presto the main solenoid kicked in and the machine came to life head drum spin and capstan spin , it was happily playing a none existent cassette.
I found the tiny bit of plastic that's broken off, i have glued it with plastic cement but i may have to glue it with 2 part epoxy.
Tape loaded for real now and playing normally !!!!
Thanks guys for your help.
