Good luck finding that damper diode though. Looked but couldn't find the ECG number. Well good luck getting it going. All the best Tom.J p.s. Nte part number for the RCA damper is ECG/NTE173BP.

Thanks for the advice. I'd like to make do with what I have so if I don't have one (I've got some real oddball pulls so there's always a chance I may have one somewhere), then I may try making another damper tube work in that circuit...I've got some wacky series string dampers sitting in boxes with nothing better to do.
