More advice, please. I am unable to locate a replacement for a Nichicon 4700uf, 100v, radial leads, 30mm diameter x 45mm height, 85 centigrade. The diameter is the problem. The newer caps are 35mm in diameter. Since my amp's circuit board has 4 packed together, there's no room for another 5mm each. I've checked Digikey, Mouser & Newark. Can a snap-in be converted somehow? Any suggestions?
