I used to use a high power carbon pile in the labs.

Big and larger than 4 lunch boxes. The carbon is compressed or
released to change the resistance.

I think 50 ohm would be a bit hard to come by. Ours was 1 ohm.

'course, with all those old gouging rods he has lying around unused, he
could make a _real_ carbon-pile dummy load...

I do have about 40 lbs of carbon gouging rods. Bit hard to solder them
together though. Could make a couple plates with holes and set
screws though...G

are these carbon rods something that can be used to make a carbon arc
lamp?

I actually do have some of those unclad carbons too IRRC .

Want to make a lamp for the Blitz?
