It is not much warmer inside as our central aircon is dead. But at least I have a hot coffee!
The next step will be to remove the optos used as level shifters to make the Arduino drive the PLL leads direct as I originally tried.
Following advice fom multiple folk, I did take the PLL board out and resolder some joints so the first try may have been ok but for a PLL board fault. Watch this space to find out.
