How are your DC heaters for V1/V2 hooked up? Looks like you have pin 9 blank? And then a separate line to pins 4/5? I've always implemented DC heaters differently because I'm using Ceriatone's DC heater board which regulates differently I think? And they have there's with pins 4/5 on each socket grounded and pin 9 is getting the source DC feed. But I'm running 6v DC and you're using 12v.
