Re: Racal Dana 9916 Frequency Counter.
Right Gents, some good news (for a change), i build Nixie and LED clocks when i am not playing with other things, to that end i have a number of nixie/led display driver ic's, so i dug out a 7447a ( see note from Richard above) and fitted that into the previously fitted ic socket, i was rewarded with a lot of 0's, so looking good, just have to wait for the correct ic's to arrive then i can re-assemble counter and give it a thorough check over.
So many many thanks to all that offered advice and suggestions. cheers, snowy
