As I recall someone put the specs for the capacitor on the forum within the last 6 or 7 months. I saw one advertised somewhere for a whopper of a price. If no one chimes in on this I will measure mine and find you a replacement for only a buck or two I would guess. It is just a simple capacitor and the application is nothing special or secret, it is just a RIP OFF to pay more for one.

Bad filters should only cause the tach to float around and not track rpm well because it is trying to also follow random noise.
I broke a wire off of mine this spring, during one of my three intake manifold R&Rs. I hooked the wire up direct, without the filter and the tach works as well, or better, without the filter.
RACE ON!!!
