TubesGlo Posted December 20, 2021 Share Posted December 20, 2021 Finally rewired my amp. It started when replacing the original tube sockets with Amphenol blade style. I installed a new stock replacement 7199 board from Dynakitparts a while ago. Just installed CDE WMF series film caps with stock values, painted them black because I don't like yellow. The choke, bias supply and cap can are new. Diode replaced the selenium rectifier. I have a near new testing vintage Mullard GZ34, four matched pairs of strong Mullard xf2's and 3 pairs of 7199's. Fortunately I read Dave Gillespie's ST-70 Baseline paper before doing anything to the amp. I'm very happy with the stock circuit and it sounds beautiful with my Crites Cornscala's . 4 1 Quote Link to comment Share on other sites More sharing options...

ned Posted December 21, 2021 Share Posted December 21, 2021 Is it for the KEF or the Heresys? I bet it sounds great. Of the 350,000 sold, yours is just about perfect. Quote Link to comment Share on other sites More sharing options...
