Fixed that typo for you.

Yes I did sub an RCA Fly 1 in a Mayflower 10" set, it worked great but that set uses all the same tubes in the horizontal and HV section that the RCA does, not sure if your model does or not, i.e. 6BG6 sweep, 5V4 damper, 6SN7 oscillator, basically the same circuit as the RCA, had to change the yoke network to match.

The Fly in my set was fried to start with and it looked it, it also went up in sparks when first fired up, if yours doesn't meet any of those criteria then I would suspect something else may have quit, possibly the Horizontal Oscillator?
