Subject: Re: [Amps] Drake L7 issue
On a second pass of the schematic, it looks like the fans are not ground
referenced with either configuration, unless there's path I cannot see.

## u are correct. There is NO grnd reference. in either config. Same
deal with the drake L4B amp.
## What is interesting is C41.... the 47 pf cap thaat goes between the CT of
the plate choke..and the bottom of the plate choke.
Im guessing its wired to the CT of the plate choke. What is its purpose..and
how does it work ?? Looks to me like something, such that the choke wont
series resonate on any ham band.
Does anybody know what the total uh value of the plate choke is..or where the
tap point is ? Where does the choke series resonate at ?
