Any interest in seeing some Dumble Tweed Deluxe photos?

I think the 33m and .047 cap you have on V2 is wrong on your schem
OP says

The 3.3m in series with the .002 cap is a negative feedback loop on the plate side of the phase invertor. Probably to control oscillation and maybe roll some high end off.

Hmmm.... Not sure about that....

The cap you're calling a .002 looks like a Panasonic which are physically smaller than the Sprague O.D.'s. In fact it could be a 0.1uF

I've never seen Dumble use a small cap like a .002 in a feedback network; maybe someone else would like to add their $0.02?

Hello, at the time (about two years ago) I documented the amp I was very careful about reading the caps and getting the values correct. My notes say that it was a .002uf/630vdc.

Yep, the cap is the NTE MLR mylar/poly .0022/630V

Thanks for sharing the info Charlie, much appreciated. Though I'm wondering what HAD does to a Champ, that would be interesting as there is so little to play with.

Pretty cool sh#t. A cute little starter Dumble. I feel like a little kid who stumbled upon some cooler kids w/ a bag of weed and we all went to smoke some out behind the maintenance shed. Thanks for the hit.

Thanks to Charlie.
I thought that I'd re-post this link to a video of Kenny Wayne Sheppard talking about his Tweedle Dee . It starts at 19:25
