Amps on Older ZW's

The total amperage is for all four posts. My 3 ZWs, now retired, all produced 180-190 watts or just over 10 amps totql when operating continuously. I only used the "A" and "D" posts which were fused externally with cartridge fuses. I had 0-15 range Ammeters wired inline[Series]on both the A and D power districts. As a result, I could monitor what share of the ZWs total output capacity[amps] each power district[or post] was consuming.

Thanks Dewey. Appreciate the quick response.

All four binding posts, A, B, C, and D use the same transformer on the inside, so splitting the load does not make much difference.  The transformer is tapped by little carbon rollers all rolling on the same windings.  

Thanks Dave. I wasn't sure if spreading it out over 4 posts would ease the load but I see your point.

In one way, spreading the load does help.  The highest resistance path in the transformer is the carbon rollers and the associated wipers to connect the arms to the rear posts.  So, less current through each roller contact is actually beneficial.
