Re: Dumbleator Layout
Anyone have a source for the white co-ax?
Also is it possible to get a link to the schem to go with the layout?

I thought about adding the schematic to the layout..Drawing updated w/ schematic..
If some of you have part # for Transformers used or can be used Send them along I'll add them as well..

I thought the schem would be good. Some values are hard to read (pots) so the schem is good. Very convenient.

Re: Dumbleator Layout
Very nice layout Tony. Great work!
Re: Dumbleator Layout
Groovy!
Re: Dumbleator Layout
Looks great!!
A typo on the feedback cap. .22uf. You have .002uf. Also plate has a .1uf off of it and you have .05uf.
One question... Why do people, not just here, insist on using a 470pf to bypass the 220K grid resistor? Also seen in the amp layouts. It is almost always a 500pf (don't think 470pf has ever been observed). These are commonly available fwiw.
Also, the cathode resistor for the recovery amp has been seen at 1.3K, but also 1.5K, and 1.62K In other words, it is not written in stone.

Hi Tony, here is an alternate layout that works as well. This includes a bypass and i used a 390pf for the drive bright switch, which I can use as opposed to the 1000pf.
