Helping a friend with a TL-922. On 80m, it is suffering from not enough loading capacitance. The peak at low drive levels is at 1. If driven to 1kw the peak it not attainable, as it appears to be pas

No, it is just the opposite. Grounded grids require LESS drive. It sounds like your padding capacitor is wrong, missing, or bad. It can also be the switching that kicks it in. I recall reading in the

Thanks for the reply, Lou. The first thing I suspected was the padding capacitor for 80m, or the additional portion of the loading cap that is switched in on 80m. I checked all the capacitors, as wel

Added inductance in the grid lead makes a tube *harder* to drive. Compare the 811/572B and a ceramic triode like the 3CX800 or 8877. For good info on the TL-922 see the information by W8JI: http://ww

On 80m, it is suffering from not enough loading capacitance. The peak at low drive levels is at 1. If driven to 1kw the peak it not attainable, as it appears to be past the lower limit. I suspected t

I have always had a similar issue with my TL922 on the CW portion of 80 and the low end of 160. I too checked everything, including the capacitance of the padder, and found nothing wrong. I finally r
