thank you - voltage before the 5 V regulator looked good, about 16 V so transformer and bridge rectifier seem to be o.k.
There are a few tantalum capacitors on the control.board which I will check.
Next I will have a look at the diodes - half of them are heavy 10 W screw-in types and can easily be removed for measuring.
Next come the bridge rectifiers.
