Mike -
I know you have lots of tubes ..... :-)
Try a 6EA8 in place of that 6U8 and report back!

Hi Folks,
I'm looking for a little direction with a problem I have with my 2B.
It seems that it is intermittent on 15 and the middle 10 meter band.
They share the same crystal. I've replaced the crystal. I've cleaned
the switches. I've replaced the 6U8 oscillator tube. That worked for
a while, but now it's dead again on those bands. The crystal
oscillator is definately not oscillating. I've reheated solder
connections. The resistance and voltage measurements on the 6U8 are
pretty close to where they should be. I guess there's a resistor that
has drifted or a leaky capacitor. Is there anywhere else I should look?
