ESP 3A amp

Thanks for the responses. In the assembly instructions Rod states that C1 can be anything from 1 mf to 10 mf. I have two caps in hand which fit the bill. One is a 4.7 mf electrolytic, the other a 1 mf metal film box cap.

Question: Is there anything to recommend one over the other or does it (as the instructions appear to suggest) really not matter as long as it is between 1 and 10 mf?

Thanks again
Steve
