[time-nuts] Trimble T-Bolt Power Supply Question

[Bruce Griffiths]

I have used one of the Cisco34-0874-01 supplies to run a Thunderbolt for 
a couple of years.
It appears to work well.
However I haven't measured the resultant 10MHz output phase noise spectrum.
I am about to power another Thunderbolt with an open frame linear supply 
(723 regulators with 2N3055 series pass transistors) so in  principle 
comparison of their output phase noise spectra should be feasible (when 
I finish designing and building the required low noise post mixer preamps).
