Default Any info on 3572 Half wave Rectier

Anyone have any of the specs for this tube.
I belive it's 2.5 volts, anyone know how many amps it's rated for.

I've never heard of such a tube.
What is the size? What type of socket?
Are you sure that you're reading the number correctly?
Could it be a 35Z3?

It's a 4 pin tube, Globe shape.
I believe it's a Mercury Rectifier.
I won an ebay item (249A Mercury Rectifier) and the guy had a pair of the 3572 as well. I thought I had seen the number come up while seraching the net, but can't remember where.


It's a poor pic.

Looks very similar to the globe 866 rectifiers.

Yes it does look very close to the 866. I have a few Globe 866 + 249B Tubes. I'll have a better look when I get them, I'll check to see which pins if any are not connected.

I think (hope) it may be rated somewhere within the 866 + 249B specs. Hard to find any info on these, I'll say more rare than the WE 249B I guess!!

Thanks for the input guys.
