In Reply to: The MA-230 is the single worst piece of vintage gear that I have ever heard................................... posted by viridian on March 10, 2010 at 13:26:25:
Need a Mcshane rebuild kit with the doubler caps and extra decoupling and ground scheme and selective resistors in the phase splitter. Talk to anyone that has rebuilt an mc240 or had one rebuilt with Jim's kits. We use paper in oil caps(k40s) and a couple film caps but the difference is so phenomenal from stock that,you increase the performance of EVERY aspect of that amplifier.
Now,the 230 responds well to the cit 5 kit but you also need to change the 12au7s to 6cg7s and,you need to recap SS preamp board with film caps and oilers and non polar muse caps.I also put in hexfreds but thats a matter of taste.
