I am looking forward to seeing if changing out the 3 resistors, 3 capacitors and transistor fix it. Did you get a new coil as well as these can be a problem if they are overheated or burnt out. I have all the bits, just haven't had the time to do it.

Only thing is, I swapped a working clocks PC board into a non working clock and it didn't fix it.... the PC board components may be on their way out but still run a slightly weaker clock mechanism.

The clock mechanisms seem to work fine so it has to be the electronic part that fails.
