No. No modifications are necessary to use the 6GJ5. Pin 8 is no
connection in the 6GJ5, and is the suppressor grid on the 6JB6, which is

Carl, Check the filaments on the finals. They are all three in parallel and
drop the 12.6 volts to 6.3 for the remainder of the tubes. The wires to the

Hi to the group,
T4 is getting there...have the new AC-4R board kit on the AC3 unit and now
when I turn on the rig at least I don't hear the transformer windings bang on.
Board was easy. I had to scrounge a bit for the correct color wires with

Progress!
The 6GJ5's will work fine on 10M. Try and get Sylvania, Zenith, RCA or
GE brands if possible, and best if all three are the same.

Hi Garey,
Several people have advised about the no top, including yourself I believe

I am guessing that with the AC4 board, your AC3 no longer has the test
point that mine did (if your had it at all). On some of the AC3s, there

Hi Ron,
The only test point indicated was on the high voltage output on my AC3, with
