Really nice, Jack. Did you use the Ranger audio system to
drive the 813s?

Such a project is never really "finished", because there are
always new ideas and parts to be tried out.

Roger. I started a thread earlier on using 813's as triodes and it was
like falling off a log. The modulator consists of a very small chassis
with a fil trans, tube sockets and a meter. This sits next to the mod
iron on a wood deck. I like the idea of the mod iron isolated from ground.

Roger again. I want to eliminate the Ranger for one thing starting with
the audio. I bought a 4W audio pre-amp and when I get tired of playing
with the new rig I want to see if this will drive the 813's. I need
some ideas on interfacing the two... some sort of interstage audio
transformer I suppose.

Then, a simple xtal controlled exciter would be fun.

No end is there?
