Looking for one in the 500 to 1,000 Watt output range. I would like to use
it on 160 and 80 AM.

Considering the weight issue, something in Southern Arizona would be

Tnx, Dick, W1KSZ

I've not seen THAT one before, but they did power some largish tubes.

8877 power supply is 4kv at point 8 amps.

3k supply is 4kv at an amp

I've seen plasma therm boxes with tens and fifteen as well.  They are some of the bigger rf gennies.

Didn't know he was sick, as I've been not doing much radio in recent weeks. Best wishes for a quick and complete recovery!

Ok, so this strapping supply followed me home.
Very low price, from NYS auctions. My tax $$ coming back. The main warehouse is 1/2mi from here. On occasion
there is good stuff to be had.

It takes 208vac single phase the entire box is rated at 30 amps!
some of these PS units apparently powered up a 3CX3000 tube... no idea what this one was running.
No solid documentation could be found online. Thermal Jarrell Ash is the mfr... never heard of them.

... of course I don't know what the HV voltage is, and will have to do an actual check of the iron and the B+ (if I can),
the whole PS may have an enable link from the main unit.

The cabinet is very well built, sitting on casters and made of what looks like 0.20" aluminum.
It has a neat top/front cover, and a side that lifts out (shown removed in the pix).

So, what to DO with this??

I could hardly hear Tim this morning.

Al, I was hearing you OK FB.

Hopefully Tim makes a quick recovery and fires up one of his big rigs so I can hear him.
