Univolt

I realise that 40+ year old technology has been improved upon in the time interval, but just how "evil" is that old power source? Should replacing it be a high priority, or only something to keep in mind. The buzz is not that annoying when I take out my hearing aids.

Replacing a Univolt should be a high priority. The newer multi-stage charger/ converters will not fry your expensive batteries, like a Univolt will. If you happen to forget to top the water off in your batteries, and leave the Univolt plugged in...it will boil the battery dry and make a big mess.

Looking for a good thread (lots of pics and instructions/tips for electrically challenged) for doing this replacement.

Two questions: can you read or interpret a schematic or black diagram and do you know how to use multimeter?

Yes, you should replace the Univolt. Go to the Forums tab, click on Electrical and you'll see a permanent thread on Univots. Tons of good information.
I replaced my Univolt with an Intellipower 9245 and am very pleased with it. It was a pretty simple process with only a little confusion on my part. Fortunately there are a lot of people on this forum with a lot more knowledge than I have and they are willing to share.

I put my univolt on a timer and charge my battery for 2 hrs per day when camping. I have not ran out of power or damaged my battery. Not sure if this is an option for you but it has worked for a few years for me.

I put my univolt on the end of a rope... It makes a great boat anchor. .

I would upgrade as current technology is much improved.

I didn't find the permanent thread but I did find plenty of others and shared experiences with replacement.

Somehow I missed this piece of wisdom 3 years ago when I got the Argosy. When I am not using it I have it parked in my driveway and it is always plugged into the house power. The marine grade Interstate battery was new 3 years ago.

Fearing the worst, I pulled the battery and to my surprise the water level was still good and and the battery nearly fully charged.

This seems like a fairly inexpensive upgrade and while I've grown used to the buzz, this is now on the to do list.

Most of the replacement threads have opted for the PD9245. A small few have opted for the 4500 series which is an all-in-one panel.

http://www.progressivedyn.com/all_in_one_pd4500_1.html

Would anyone care to comment on the tradeoffs between the 9200 and 4500 or going with the 60 amp vs 45 amp converters?

Univolt

45 amps is plenty for your coach.
I would highly recommend a new fuse panel as well. Whether it be a PD9245 with a separate fuse block or panel. Or a unit with a built in fuse panel.

On the old Airstreams and Argosy's the PD 92xx series is the one to use. If you are replacing the ones in the newer Airstreams which have a Paralax all in one power center (120 volt breakers and 12 volt fuses in one box) then you use the PD 46xx series. I am not sure when Airstream changed to the Paralax system, sometime in the 90's or early 2000's I think.

A 45 amp converter/charger is fine, a 55 is also OK. No reason to go any larger.

So a PD 9245, or 9255 for the old units, and a 4645 or a 4655 for new ones.

My 2001 Safari 25 has the AC panel in the back under the foot of the roadside twin and the DC panel in the front. I replaced my parallax 9255 with a PD9260. Straightforward job. Two AC connections, ground wire, 2 DC connections and done.

Would have been easy-peasy except that the AC outlet the converter was plugged into was bad. It was on the center of the forward wall inside a custom storage cabinet that the OO had put in between the two recliners. Working at arms length inside the cabinet, couldn't see what I was doing.

I went with the PD 3-stage charger because dumb chargers were killing my boat batteries. Since changing to a three stage, they last as long as car batteries, 3 or 4 years. The Parallax was not as dumb, but I drank the Koolaid and swapped it out.

But it's all good since the fix.
