RE: Capacitor between DC amp and preamp?


Might be easier just to replace the amp caps since there is already space for them.

To figure the value you need to know the input impedance of the amp. The minimum cap value would be 1 divided by 2πFR where R = input impedance of the amp and F is the lower cutoff frequency. Larger is OK and lowers the cutoff frequency.

The voltage can be low since it normally only sees DC.

They type is open for debate but definitely not electrolytic.. I like oil/film motor run but they can be physically very big. However, since you are talking DC they could be mounted between the 2 pieces since there is no danger of getting shocked.
