Curt - That is yet another way. I'm not sure why using reduced loading would make the output non-linear It's a 'linear' amplifier which implies that it's 'linear' from zero to full output. It may be that one of the lower level stages are distorting, but I'm not sure why they would. Us

This is just my own experience running a T4x into a KW linear that needed 30W of drive (pair of 4cx300 grid driven) While the T4 loading control will reduce the output, it tends to make the output non-linear from the T4X. It is better, signal quality wise, to tune the load control properly a

Garey, Hi... I was just reading a post you made on reduced drive to the L-4B from the T-4any. You mentioned having the load at 0. Are you talking the T-4any or the L-4B as to the loading on 0...I suspect it is the T-4any. What if we load up the T-4any to a lower power out by putting the load
