New Ranger RCI-69VHP SSB coming soon

Eldorado828 said:
Anyone here have experience with these rt1 transistors from ranger? My questions is bias voltages, what would we set the bias voltages at? Under 4 volts like the 520 I can guess. I ask because a coworker ordered a 39vhp and asked for me to convert it to 11 meters for him so I plan to check bias voltages because I've seen them way high or way low from the factory. Hopefully someone has had them on their bench.

In my experience 3.2 to 3.5 volts is where they are after I set the bias current.
Also my 69vhp has been rock solid stable since have had it, winter temperatures will cause some drift on warm up I imagine.
