Gregb, thanks for the offer. I'm going to wait for the new tube and capacitor, and maybe rewind the coil one final time, then I might have some questions.
It isn't green death that will be your problem, it's black goopy celluloid death  Maybe the lack of problems so far is a function of Canada's climate? Even then, it will probably fail eventually.
As far as component values go, I think there are incredible tolerances in (most of) these circuits, but I would recommend highly against toying with anything in the 89 oscillator...
