Does capacitor size matter?
Ok but here is the part that I thought was odd it was a 370v rated capacitor, but the unit is a 480 volt unit and the cond. fans were 480v also. I did put 440 volt caps on. So I get that technically there is 277 volts across the capacitor, Which is good cause I don''t see many 600v rated caps. Also don''t know why this didn''t strike me odd …

Tweeter Capacitor Chart – What Capacitor Value to Use for …
Experts recommend adding a capacitor in the positive line to the tweeter as a crossover, ranging from 0.47mfd to 1.5mfd. The lower the value of the capacitor, the greater the crossover will be, and the tweeter will sound quieter. If the tweeter is still too strong after experimenting with various capacitors, try adding a 1-ohm resistor in series …
