The converter/charger I have is a Magnatek 50 amp, series 900, model 950. From what I understand, Magnatek makes one of the noisiest units around, and it's likely that no noise filter known to man can filter it out. Replacement is the only way to go.
BTW, no filtered outputs. This looks like a rather primitive model with only two leads out, which connect to the
12V fuse panel.
Checking a local RV parts supplier's catalog, I see a 55 amp model by PPC, and a 45 amp model from Progressive Dynamics. Both are supposedly filtered for quiet power and are similarly priced. Just wondering how I select the amperage since I have a 50 amp model which seems to handle the load, and the only models available are plus or minus 5 amps. Total up all
12 volt loads and get the next largest model?
Any comments on either of these brands would also be appreciated. I know that Progressive Dynamics is supposed to be good, but the PPC unit looks like it will be a better fit.
I have two house batteries which will be charged at the same time. Not sure how that affects things, if at all.
Now let's say I go thru the expense of replacing the converter/charger just for the sake of having a nice stereo system, and want to recover some of the expense. How much could I expect to sell the old Magnatek for?
