[AMRadio] Elmac A54

[CL in NC]

One thing you get when you ask questions on some  sites about gear, is a lot of pontificating, useless suggestions,  and no info.  Amphone always seems to have more meat on the answers. On the Elmac A54 meter for plate current, it has a 150MA scale, and a tic mark at 100MA.  I seen no mention of the scale being X 2, the actual tune up procedure in the manual,  says load to 300MA or as near as possible, that has to be a misprint.  On one site, a fellow puts 600VDC into it and loads to 200MA.  That seem like a heck of a lot for a single 807.  

Other comments say the plate tank is designed for a whip antenna, and not a 50 ohm load.  Is that a true statement?  The one on the bench right now I'm working on, I put 450 VDC on the plate and am getting about 35 watts out, but the load cap has minimal effect, like none, you can set it anywhere and does not change plate tuning but a tiny bit, and still gives 35 watts into a dummy load.
