- Some questions about MLA2500 operation on 160: I am interested in better efficiency. More output without increasing present input, or maybe less input for the present output. 1. What is the purpose o

- Tom, Is a Q of 8 enough to provide sufficient harmonic rejection/TVI supression, etc? All of the "how to build a linear" articles I've seen over the past 40 years of the magazines (I had a fair size
