dustie1	Re: Matchless Clubman squeal Thanks for your reply.The only schematic for this amp I could find was on duncans site and is different from my Clubman 35.Mine has a EF86/6J32P in V1 and some of the caps and resistor values are quite a bit different from this drawing.The amp has never been opened up. I checked the voltages on V1 and found : Pin 1 = 52.7V Pin 2 = 0 Pin 3 =1.5V Pin 6 = 124.8V Pin 8 = 0 pin 9 = -.06 I am a first year electronics students so know how to work safely in the amp and understand what the components are and how they work but not how they work together and my trouble shooting skills are poor.What is the best way to check a cap for leaking DC?I do have a good meter,a fair scope,dummy load and signal generator but have only used the scope and generator on low voltage DC circuits.(15VDC) I'm here to learn. Thanks
