Has anyone tried powering additional circuitry, e.g. a GPSDO, from the existing power supply in the Extron 6 300MX?  I measure ~ 17.5V open circuit, 16V loaded by the distribution amp.  Would like to piggyback a TruePosition GPSDO board on the same rail if I can get away with it.

You probably should use a little separate  power supply.
Below are a few pix of mine.  I have a little 12V supply and the GPSDO mounted on the bottom plate.  I connected the 12V supply to the same AC input so it still only needs just the one AC input to power everything.

Of course, since it's a GPSDO, I drilled a hole for the Antenna input on the back.  Cut a rectangle on the front to insert the LCD display.
The first 3 rows of BNC's on the back are all for the 10Mhz.  The bottom row of BNC's are for the 1pps signal.
