Deang Posted April 10, 2013 Share Posted April 10, 2013 He's got room on those networks for some nice new autoformers. Will he hear a difference? I honestly don't know! But it just doesn't seem right to have all of that new shiny and not do something about the rust. The scary part is that he used copper foil, and I've been telling everyone that it doesn't make a difference -- I use the aluminum foil versions. That's a crap ton of money sitting on those boards.

KT66 Posted April 13, 2013 Share Posted April 13, 2013 As the AK-3 looks now with Clarity cap & Mundorf cap, a new bigger board and new mid 5mH choke. Shortly to be modified to take a new mid Tractrix horn and 2" driver & new autotransformer. See separte pics, unable to post more than one at a time - the add button replaces previous pic.!

KT66 Posted April 13, 2013 Share Posted April 13, 2013 ESA Clarity caps are have the silver labels Mundorf caps are on top as bypass ( ~10%). 12:1 You can just see a grey Vishay 1837 bypass across the far cap ( tweeter series trap). Check out the above two views. Quote Link to comment Share on other sites More sharing options...
