Hello LF'ers, A very happy Easter to everyone! I have a tech question tthat I am sure you more experienced operators can answer. yesterday I mowed the lawn and found some of my temporary earth leads

Chris, I assume , due to the Q any small variation , will move the tune point about , but looking in the data base , Signals , better last night to sv8 than the previous night , and may be up 1 db at

I don't know why more designs based on them haven't appeared.  Other than my half bridge version running from 320V DC from raw rectified mains, all the other high power amps around seem to use the cl

Hello Graham, 15 April 2017 Just to be clear, this is just the original single amp that's been fine now for ages, not two combined.... Not sure if people are thinking this is part of my two amps via
