ELNA Cerafane Randall why would you use ELN Cerafines or any elecro type cap over polypro in your amps? Is there something about the cerafines? When I read about the cerafines I thought it was all HiFi hype. The main reasons I used the Elna Cerafines was because: (a) they were cheaper than LCR and a far better cap. (b) they came with a free mounting clamp! (c) they were a cool black color that matched my trannies. Actually, the main reason I don't use polyprops is because I need eight 50uF/500V caps (four cans). The polyprops are hideously expensive, and too large to fit inside the chassis. I'm working on the fit, but I can't do anything about the price. Randall Aiken
