Good point, hj, and thanks to mbz. I've been reading the pros and cons of bigger caps and yes, it's a great debate, ain't it? OK, I'm going to abandon this thread and start another, I'm getting scattered in my old age! I will title it Kenwood KR-5600 relay/recap project. I actually have two KR-5600's to recap, the first being my own old friend I've enjoyed for years, and the second a new project with an open relay. I thought I'd work out the relay problem, recap that amp, then recap/upgrade my own with my education. I have the working model to check against as I try to repair the relay problem. Please follow along and chime in, I need all the help I can get! In the end I hope to provide a BOM list and more tips gleaned from the project, my fourth ( and fifth) recap. I just finished recapping a KA-3500 with really nice results. It's an easy amp to work on and the sound is clean, clear, detailed and strong. A lovely amp. So I was inspired to tackle the bigger project. See you on the new thread! Thanks, y'all!
