Voltage converter might be one of these :

You can also sometimes find a similar device on an old 10baseT ethernet
card, where it generates a -9V supply.

I considered float charging a battery bank and switching power supply + linear

Concern with the first is safety in charging. I was intending to use GEL cell

Yes.

Concern with the first is safety in charging. I was intending to use GEL cell
lead acid battery. 24V chargers are plentiful but there is no telling what
they actually do.

Back when I used to accumulate time nuts gear, I also used to accumulate
various linear power supplies (mostly surplus / used HP lab supplies.).
Approx 10 years later I should probably should look at the noise levels,
regulation etc again.

Hi
Each project is a different “experience”. Some things are way more susceptible
to switching noise
than others. Some switchers put out way more noise than others. You would not
run a linear supply
on a computer. The low noise front end of a radio is going to need a quiet
supply …..

It used to be that there were only one kind of switching power-supply: The
noisy ones.
That is no longer true by definition
Most commercially manufactured time and frequency sources use switching power
supply. However, when contacted, tech support for SRS says, in regards to
PRS-10, use linear power supply. I am guessing, when manufacturers design
complete units, they take switching noise into consideration and dea

Thanks, the photos helped when I disassembled the unit (the silk screen
was smudged) and have the pin legends --- I was hoping someone would
have a data-sheet or app note ... my efforts with Google have been
fruitless :-(

I think that might be a picture from ebay. The 4th photo from this item has

Hi,
With a slight different angle you can read more of the silk screen text
it seems.
Can you read the full text somehow?
I can make out GND, so that is a good start.
Cheers,

Thanks Didier,
I have same manuals 2509xyz but this 11729C is 2641xyz and looks totally
different.
So I am looking specifically for the later one.

The microusb on the side I assume does the external power.
