[Collins] Collins ARC-2 Question - power supply

[Greg Mijal]

Hi:

Got a couple of question on the Collins ARC 2 am transmitter-receiver.  I'm about to lite the candles to the one I recently acquired.
It looks pretty good inside with only a few modifications.  It was modifed in the past to operate without the dynamotor.  The power supply I built up load checks ok for plate and B plus load but I'm not sure about the 24 vdc portion of my supply.  I can get 5 amps out of it on the low end of the 22-28vdc spec and it's the source of my question.  Do I have enough current to lite the pilot lamps inside the tubes and spin the channel selector motor at a reasonable speed, all at the same time? I can live with slow motors but get a bit antsy about the possibilty of dragging my DC voltage transformer into oblivion.
Here's another thing I noticed,  I'm reading 15 ohms from the power cable wires to the distribution points in the rig.  The set does have series chokes in the supply lines but read only 6 ohms. so where's the 10 ohms coming from.
The last time I fired up a major piece of aircraft radio stuff, I was 14 years old and the old ART 13 caught fire out in the garage.  My parents nearly killed me over that!
Thanks a bunch
