Very helpful - thanks to Tom & Tom.
This unit does not have VR modules - the power controller is one circuit board
about 6" long, and it has been badly burnt.

Thanks for the detailed reply. As I have said befire: No good deed goes
unpunished. So another question.
How do I get Timelab to sit up and play nice?
I have the TICC cranking away with 10 MHz ref ans 1 PPS Chan A, both from the

I have finally got my RPi NTP server set up referenced to a Thunderbolt
PPS.

ntpq -c kerninfo
my output is:
associd=0 status=0118 leap_none, sync_pps, 1 event, no_sys_peer,

reference. On two boards, C414, 3300 mfd 35 vdc had to be replaced with new
3300 mfd 50 vdc units. One board had a good C414 with
