Hey guys, I just bought a Context 500 for use on 11 meters in my new little shack. Does anyone have a manual for this or know where I can get one? I am looking for information on the tuning procedure for setting the drive and the load etc. I assume it would be the same as any other amp? It has five 6LQ6 tubes and appears to be recapped. I don't have it in my hands yet, just trying to learn all I can about it. There is surprisingly little information about it when Googled. Any and all comments welcome. This is not the actual unit, just a picture I found of one.
