Hello Fellow McIntosh fanatics! I am currently working on Restoring my first MC240. I have already gone through the PS Section and am currently measuring all of the Carbon Comp resistors and Capacitors. There is some debate o whether to leave the Red Lettered .22uf 600V Black Beauties in or not. I am measuring mine and they're coming back at around 1uA of leakage @ 600V. What value is considered not acceptable? I am being advise that given their age, I should replace them as the Caps are now over 55+ Years Old! I would replace with a combination of Orange Drops and Russian K40Y Capacitors. Thanks for your feedback in advance!
