That particular amp was at Maken Music for a number of years and was purchased by a well known guitar maker for over 30-K. Must have been because of the road case .
It's wasn't a particularly great sounding amp, or so I was told.
Not sure of the topology or circuit vintage, but I eventually heard it few times live, and been unimpressed.
My vote is for filter cap, not rectifier tube btw. I'll ask someone who might know.
"I actually don't know about the circuit or the mystery "tube". All I really know about the amp is that it was serial number 175 and it has Mercury Magnetic Trannys and EL-34 power tubes. Dumble told Greg (Bales) which specs he wanted for the transformers and Greg ordered them. The amp took 6 years to deliver. When I got it the woman who shipped it to me had sent it with the foot switch in the back and the tubes were broken. I installed some Boogie tubes in it for a while and did not initially have it fixed up because a shitty sounding dumble sold a f*ck of a lot of Fuchs' for me Eventually we put some NOS Seimens tubes in it and got it sounding a bit better. Paul told me after I sold it to him he had Dumble install a "skyline" preamp for some ridiculous amount of money. The last I heard he sold the amp to someone else."

Andy, Maybe I missed it (or can't read between the lines) but did this guy say for sure that it was actually a tube? It's def not a GZ34...too tall, too skinny, and I don't think you'd ever put a shield on a rectifier tube anyway (retainer...yes, shield...I would think not). But as mentioned it's weird to stick a can right there considering how much easier it would be for him just build it 'stock'.
Probably totally unrelated but I used this time-delay relay tube to build an 'auto-cycler' at work. I just copied an existing version of the same thing (built in 1969)...sure I could have used a SS relay but this just looked too cool (and the original unit has never failed). This tube above is about 12AX7 size though. Doesn't look like it will be available for long (click on 'datasheet' and you get the SS relay page).

Personally, I feel that it's still up in the air. I think there's valid arguments for both sides i.e. tube vs. can cap. The suspense is killing me!!!
Regardless of Dumble building the old or the precision power supply, what they hey is a can cap doing all the way over there? Maybe it contains the soul of SRV?

Tube relay? Whoa, never seen before. That is very very cool.
