I've blown several regulator chips in my 35a. Last time around I just bought a
handful. Simple fix since it is socketted. I hear if you tie the negative
terminal to the case/ground, it ends the problem that kills the regulator, but
it also means you can no longer run two units in series to get 24v if needed.
I went a different path for shack power using two 100ah deep cycles and a 40a
RV inverter supply (not a switcher!). Works well since the radios stay up for
about 5 days after the AC mains go down. It also takes care of the occasional
60a loads the astron could not handle.

I would be grateful to know the brand name and model number of the RV inverter
that does not use switching technology.
When I ran my Astron linear power supply in conjunction with deep
cycle batteries, I put a 40 amp rated Schottky diode on an electrically
isolated heat sink and set the float voltage at the
battery terminal.
