I'm getting ready for my big nostalgia project to fly... a rebuilt Saratoga Windsong - and I have a perfect radio for it from the same era... except this TX was just bench tested and I find out the pots on the right-hand stick are shot. Serves me right, using it like a single-stick 2/3-channel all these years on my gliders:-)
Aanyway, Polks doesn't seem to service transmitters any more, certainly not 20-year-old ones. I need either the pots, or the entire gimbal assembly from a similar Challenger 620 or 720 TX. Anybody have a source? I'm trying to not spend a lot for this... I have a guy that will install replacement pots if he could get a digi-key reference number for matching replacements.... One guy will sell me an entire 720 for 50 bucks, but that's steep on my budget, I was hoping to find the pots for a couple bucks somewhere...
Help!
