I am looking to build one of these. Info is pretty scant - Do any of you have one? any gut shots would be extremely helpful as I am trying to work out if there are filter caps and what values they might be. Also if anyone has a clue to transformer specs that would be great.
Thanks in advance!

Re: Volu-tone Model 5 Questions
I've heard of the Volu-Tones, but never had or worked on one. The filter caps are shown just below the choke in the schematic; maybe a 2-section can type, and values would have likely been 10-20 mfd.. I'm guessing the speaker might have been a Rola, as they were pretty common back in the 1930's, but I've alse seen a few Jensen and Utah speakers used in some similar early amps.
Maybe someone who has one or has worked on one can give better info.

Re: Volu-tone Model 5 Questions
Thanks for taking the time to help out, much appreciated Donny. Hard to say as the filter cap values in old radio's are pretty small... I will have to do some experimenting once I can find a suitable speaker and will probably have to get Heyboer to wind the PT for me.
