Good day all!

I have purchased a large number of tubes over the past many years, I've forgotten about one in particular that I have quite a few in NOS shape, with a black steel casing that is rough is rough to the touch... even the packaging is mint!
These radio tubes are made by Rogers after 1944 in Toronto, Ontario Canada. I can find virtually no information on them aside from that they convert AC to DC, and have no idea of there worth nor what I can substitute them in/out for.

The tube is Rogers Radio Tube 6H6M

Any and all information would be appreciated!

Cheers.

Its a sprayed conductive coating. As mentioned, functional equivalent to metal tubes but they didn't have to pay for use of the RCA patent.

6H6 looks to be more of a detector tube, useful for FM tuners and that kind of thing. Some VTVM might have used one. Later gear would use something like a 6AL5. Its not a power supply rectifier.
 
They are 2 little indirectly heated diodes in a single tube. The smaller 6AL5 is what's used today. They were often use as detectors and AGC in radio circuits. Not much use for them today except as replacements in equipment that uses them. Not an audio tube at all.
