Hi All,
Having just got to testing my pair of Gi7bs on 144 MHz, I notice it oscillates
quite happily at 478Megs.....
The amp is built to YU1AW easy build design, with one slight modification - I
am using a 100pf doorknob as the HT decoupling cap.
Swinging any of the controls has no effect over frequency or power of the
oscillation.
I have relocated the anode RFC so it has shorter leads, the grids are well
grounded with brass collets that cover 99% of the grid connection and are well
bolted to the aluminium chassis.
Any suggestions would be well recieved!
