Ebay 300638681652 is more like it. Just add a 7805 to get your 5 volts. For
that kind of price it's almost cheaper to buy than to pay for gas plus time for
me to go to my storage unit and grab one (maybe that's a lesson for what I
should even save!).
In my intended application though, there is already +5 and +15 available.

Subject: Re: [time-nuts] Ebay FE-5680A Rb I see the price has gone up for these
FWIW. I just hapened on this power supply in an ad. You might find a fixed
voltage one somewhere cheaper, but the price seemed ok, so here it is for
consideration...

Still need the 5 V somehow, so not a complete solution for the 5680A.

This thing requires plenty of current to get started.
My Tek CPS250 1.2 amp output (A+B parallel) only gets 7.5 volts.
Now to scrounge something a bit bigger.
---------------------
The 15 volts to pin 1 starts off needing to supply around 1.7 Amps,
eventually falling to somewhere between 700 and 800 mA.
Pin 4 always draws around 85 to 90 mA from its 5 volt supply.

I trust that you are aware that some models of the FE-5680A only require
the 15 volt/1.7Amp. supply. In fact connecting a 5 volt supply to the units
that are programmable can cause damage !
