The wattage or tube count is a question I've asked myself too.
I have stuck four unmatched 6V6's into a D'Lite and I didn't hear any great changes other than the difference in tone expected between 6L6's and 6V6's. Normster has said said four 6V6's sound bigger than two 6L6's, so who knows?
More listening is required by myself.
I'd like to see the Super Overdrive Special added to the chassis. I don't want "made by Dumble" as that would be misrepresentation and ratio of the lettering doesn't have to be the same as a Dumble, but it does have to look good. Presently the omission doesn't look good and should be addressed. That's my two cents as a consumer. 
 
 
How do these chassis' compare to Nik's chassis?
Nik's chassis are well presented, Ceriatone is successful as he's married a low price point with a reasonable level of quality.
The R&D is another issue. Still a lot of people have built amps they might not have otherwise built?
Oh well?
