H.A. Dumble drawn reverb schematic
Maybe this is old news, but I bought an updated Aspen Pitman Tube Amp Book last weekend, and it had this schematic in the Valco section. There's no other info about it, so I don't know if it's a Dumble rendering of a Valco reverb, or if it's one of HAD's circuits. Anyway, here ya go.

I don't have no info either Rich,But I've had the Tube amp book for a couple of years now and never notice that until your post.Hope someone can shed some light on it though. Chad BTW I believe it is in the Supro sect. but I'm sure it was just a typo 
Re: H.A. Dumble drawn reverb schematic
Rich,
I think it is a Supro 500R Reverb Unit.
Just look at this page:

Almost all the way down there is a reverb unit. My guess is that HAD was studying other people's work.

It is Alexander who did the schematic, not his unit though, Supro
