- The control of PA current is derived from a R in the A+ line to the PA. The voltage across the R is fed to the 2nd mixer board and driver which reduces drive inverse to the PA current. The current ne

- This seems to be a very clear explanation of how it is done, based on actual analysis of the circuit. Thus it seems reasonable to accept that this is how it works. That being so, I wonder why Ten Tec

- Curiously this system is not used in early TT rigs -- Argosy, which has a trip in the PSU or a Airpax. And the Omni D (but I'm replying on memory for that). I take it you have tested you hypothesis b

- I can't find my Corsair II manual at the moment, but I've not observed that collector current reduction in my Corsair II. Given a bad load Z it simple blows my fuse protector. 73, Jerry, K0CQ _______

- As I recall, and I don't have a manual in front of me, the Corsair series and the Delta series did not use current sensing the similar way that the Omni and Paragon series of implementation. Thus the

- Excellent thread highlighting a unique TT feature. So TT introduced this feature after the Delta/Cosair (and the Argosy) which seems to put the timeframe in the mid-1980s (perhaps) with the Paragon 1
