Q for ampdoc1

[ampdoc1]

Tubedogsmith,

I want to ask, "What is it about the schematic I posted that is more correct than others that are available?". Since I did the takeoff myself, I know it is very close to 100% authentic, allowing for human error.
Inquiring minds want to know.

Hey David,
What is the value of the cap across the plates of the PI? Is it 50uf or 50pf?
That's one thing I've never seen in any of the other schems.

Thanks,
Thomas

Thomas,
That is a 50pf cap. I've got both my original take offs, and computer generated copies of all them ready to have Omar put them on the site. It will be a lot easier to read, and I've corrected the two little things that I had wrong on the A1b schematic.

The pot values are correct, the phase inverter, power amp is right too. A couple of the small part values could be different in any individual amp but I knew you'd really been in one and knew how to read what was there when you posted the schem.

Omar,

I have readied a file with scans of my original take-off drawings of the Kelly '90 amp and more usuable computer generated drawings of the same. ~ 2 MB mile zipped. Tell me how to send these to you for distribution.

I have posted David's Kelly schematic and layout in the Files section. It's under "Schematics and Layouts" in the Main Schematics section. Thanks David for you contribution!
