Dick thank you for answering my previous question on Alpha Amp
history.....
But Now Dick, I must pipe in my 1/4 cents worth.
How in heavens name do I get my (374) not the A 3 holer to work 12 meters
and not blow up the plate choke.?
You hint in your statment that 25-27 MHz operation is possible with the
appropriate "modification"
Any chance that you can share that modification info with (me at least)
the group.
73,s
And Thanks in Advance
Steve
