I have an Argosy that has a Univolt supply.
Mine was installed in a cupboard under a shelf back from everything. It was mounted on 2 wood slats and the front was not bad, BUT THE REAR 2 WAS TERRIBLE.
i HAD A BAD TIME GETTING THEM OUT. WITH THE 2 IN THE FRONT OUT i PRIED THE BACK 2 OUT. With words of much wisdom as you can imagine. How Unkind Air-Stream/Argosy is and was.
My initial problem is that the out put of the power supply was down and low. (6 volts)
On my service bench I discovered that the power transformer is and was a 6 volt supply. And an AC capacitor ( the same as used in motor starting) made the circuit a voltage doubler. Cost of Capacitor was $8.00 and I checked all the diodes and other parts. assembled and installed unit (without the back screws and all is well.
The power supply is not a DC supply it is an AC supply that charges the battery.
IT has one input fuse and several output fuses all in parrallel.
Any othe info just E-Mail me.
