probably be with an outboard power supply, and a single switch for input

tank band switching.

Also curious: Anyone ever homebrewed a DX-60?

I built a similar rig, but it was weakly based on that design.
Mine had a 6GK6 oscillator and a 6146 final. It was built inside
a chassis with the tubes mounted on a subchassis inside. The tubes
were "sideways" and holes were drilled in the chassis-cabinet for
ventilation.

I am assuming the same transmitter was described in the 1967 HB (which
was the first HB I ever bought). You might as well leave out the
AM modulator since it will be useless today. Back in '66-'67 there
were still some people on AM (mostly on 80 and 10 meters), but today
it's completly gone. Low cost SSB xcvrs wiped out AM by the mid 1970's.

I was thinking of building a simple rig again but with a 1625 in the
final.
I have about a dozen of these bottles in the junk box along with half as
many
6AG7's. The crystals will be the scarce items these days (well expensive
anyway).


Just curious why you think the AM modulator will be "useless today" ?????
I'll have to tell those AMers running DX-?? equipment to stop talking into
the mic, right?

I stand corrected that some people are still rag chewing on AM.
I never did like the screen modulator's though. No punch.
