RE: Determining the size of inter-stage coupling cap

Quote: When the coupling cap is too small you can get an audible increase in the level of the low frequencies. Some use this to "tune" a system.

I am using grid chokes.
I want to make a comment on this because I did tune it to have very low -3db point which looks real good on testing, it but in reality there is NO useful POWER in the added resonance! once I added a larger 5uf coupling, much more useful power in the lower ranges.

BTW there is nothing wrong with larger coupling capacitors as long as you have good ones :)
