I am doing a refurbish on my heavily used L112's The re-foam is complete the binding post have been replaced and now I would like to replace the caps while I am inside. I would like to stay as close to the original as possible. I have been searching for caps with the same value but no straight across match except the bypass. From what I have read here and other forums raising the voltage is ok ? is how far can I vary from the original uf and not make a major change? Next should I move up or down with the uf value just as example 5.6uf 400v instead of 6uf 200v. I have been looking at Dayton, erse and solen caps. Any and all help is appreciated.
