rrcrain Posted July 17, 2007 Report Share Posted July 17, 2007 My amplifiers are based on the leach Super amp design and are well over 25 years old. Realistically, it might be a wise idea to replace the electrolytic caps now before they start failing. Thankfully, only two caps per channel are in the audio path. One cap, a 220uf NP is in the feedback loop and if I read the manual correctly, sets the gain at 1 (unity gain?). If room permits, is there anything to be gained by replacing this cap with a poly, or is an electrolytic good enough? All of the other electrolytics in the amp are on the 100 VDC power rails.
