Tom said: >the worse neutralization system I've ever seen in an HF amplifier. It's a capacitor from the loading cap to the filament of the tube!< I would have thought with my simple mind that is more likely to make a power oscillator. But it will be highly load dependent, especially on load reactance. What were they thinking about? Or did they only ever load into a good 50 ohms? 73 Peter G3RZP _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
