[Collins] 32S-1 Oscillations & Other Troubles

[Dr. Gerald N. Johnson, electrical engineer]

Do you have RF rated 6146? I've run into some from the Electronic Tube
Company as military parts that wouldn't work at all at RF.

How is the neutralization of the driver, the RF feedback, and the PA on
20M? Does peak output match plate current dip? When peak output and dip
match that's a hint of good neutralization.

Have you neutralized the three adjustments on 10M?
