[time-nuts] Anybody want a Thunderbolt power supply?

[Bob kb8tq]

Hi

The fact is that commercial linear supplies are still out there for pretty cheap prices. The price of a usable switcher is a very small fraction of the price of a Tbolt. Noise on the switcher is a big deal. Not everybody seems to care about low phase noise on the 10 MHz. Switcher frequency supply noise has very little impact on the PPS output.

Even if you completely discount the personal effort of design, construction, and marketing, there's the issue of packaging.  Without a package, it's just an amateur effort not worth considering.  With a package, such as a Hammond box, the price moves into new territory and nobody's interested.
