Marconi TF2002B problem.

[Yorkie]

i take it that you've seen these links Al and either have fixed the faults mentioned or that they don't exist:

In solid state gear such as this, normally ICs were used as decade dividers such as the 7490 (if TTL) or a CMOS equivalent. I don't know the TF2002B at all, but if you have a waveform going into the divider chain observed on a 'scope, then that waveform/100kHz should appear at the output. I'm sure it isn't that simple, but as Steve says, without the relevant section of the circuit, we can only speculate. From what I read about this equipment, the inductors are known to be their downfall,and of course, given its age, dried out electrolytics.

You've no doubt already trawled the net and read the threads on the VRF etc.

Best of luck with it Al, and commiseration with your other hassles that you have to contend with.
