Original poster: "Jason by way of Terry Fritz <twftesla-at-qwest-dot-net>" <jasonp-at-btinternet-dot-com> Hi all, I want to build a phase shifter to control my SRSG, for 2 reasons: 1) I can be bothered to keep adjusting the disc on the axle, 2) I am a control freak. I know that they are kicking around - can anyone help??? Thanks, Jason
