[TenTec] non qsk amp

[Phil Chambley Sr.]

On the 544, I'd change R-11 from 680 ohms to 4700 ohms, or C-3 from 33 to 47 
ufd.  Not both.

As Jerry said, on R-35, you can cut the ground foil run and bridge the gap 
with a 4700 ohm.

These resistors can be 1/4 watt.

That should get you close.

Merry Christmas everyone!
