So PnL Video got back to me and told me that my Windy II Chassis has a flyback issue. No replacement can be sourced. Dead in the water unforunately.My Windy II chassis is at PnL Video. Might have different results even if the flyback is dead. Will update you guys in about a week.
I think I have a back up solution in that I have some some Wagnam Maximum Tune 2 & 3 cabs that I can pull monitors from. Not all is lost. Will just sit on the Toshiba PB7534 chassis until a stash of flybacks pop up somewhere.
