Thanks, skywave rider, that is helpful. I am hoping to begin this project this weekend, opening up my 1976 Heresys for the first time.
I noticed you have a Trends amp. I live near Audio-magus and have listened to and been very impressed by the sound of those T amps. I also listened to the Glow Amp one, also very nice. Just last week I received a Nuforce Icon, $200. Really very nice. My old amp is a Denon PMA 850 (c 1979) integrated amp, which I recently had refurbished, made a big difference, sounds solid state, but I expect it will warm up as is it burns in some.
