I don't have that capacitor on my High Speed.

Yes... When I replaced my incandescents with LEDs, if you don't remove those 330 ohm resistors the LEDs will be on dimly all the time and then flash bright on demand. When you remove them they will be of and then flash. I just cut mine off with snips. Thru the whole machine there were like 8 of them, plus or minus.

When you replace a flash bulb (or a bank of them) look under the playfield for a small circuit board. There will be two brown bar resistors on it. Just make sure you identify the 330 one... Should be clearly labeled. It's the smaller of the two.

You can either unsolder the resistor or do what I did and clip them close to the board.

There were a total of 6 across the middle of the playfield, and one up in the header behind the backglass.

Don't remove though until you replace the lights with LEDs otherwise your incandescent bulbs won't flash.

I thought of doing this as well, but I didn't want a loose wire hanging around in the area of those boards making unwanted connections. I clipped close to the board since my resistors had unusually long leads on them. I save those kind of pieces so I could put them back in if I wanted.

That being said, I plan on keeping this unit.
