[time-nuts] Thunderbolt power supply hookup

[Neville Michie]

The separate power grounds available on the TBolt may be useful to  
improve performance.
Someone, probably TVB, had comparative graphs of the TBolt with  
different power supplies.
The 12v seems to be the sensitive one, it must power the analogue  
circuitry.
By returning the sense lead of your 12V regulator to its own ground  
on the TBolt you should
be able to provide cleaner power to the unit and get lower noise on  
its spectrum.
cheers, Neville Michie
