Members Jim999 Posted March 5, 2017 Members Share Posted March 5, 2017 Hi guys and gals. My story.... Ok so I got a JCA 20h gave it to a amp guy to do this mod - http://s150.photobucket.com/user/TnPaulMan/slideshow/Brown%20Eye%20Mod%20-%20JCA20H Got it back and it sounded awful. Took it back. He checked it all out and he is confident that it's exactly as the mod says. It cost me £180gbp for the mod. He still has the amp but he's tearing his hair out trying figure out the problem. Any help advice welcome Jim Link to comment Share on other sites More sharing options...

Members Cornholio Farquarth III Posted July 29, 2017 Members Share Posted July 29, 2017 It's too bad they don't make these with 6V6s. I'm not a fan of EL84s. Link to comment Share on other sites More sharing options...
Members spunko Posted July 7, 2019 Members Share Posted July 7, 2019 Hello, I know it is an old thread. I have searched all over the net for a guide/schematic to do the clean mod for the JCA20H and unfortunatelly all the links are broken/down. I'm really interested in all the mods I could do to the JCA20H I recently bought Thank you for the help. Link to comment Share on other sites More sharing options...
