I am not sure what AA receivers means. Boy, it sure
looks like series type grid leak bias.

That would be All American 5 tube line up. And not %. I
do that my self some times. The hot chassis tube line up
and circuitry patented by RCA.

Did I get that right?

Thanks, All American is obvious once pointed out:-) I
found the S-38B has the same arrangement.
