The Canadian Mallory electrolytics (80 ufd @ 450V) eventually reformed okay. Leakage current for each eventually dropped to 0.1mA at 450v after an hour for each. These capacitors were initially reluctant to come back: at first, when only 20VDC was applied, the leakage current was already 5mA and the current initially didn't appear to drop significantly. However, as these capacitors woke up the currently dropped right down.

I am now confident all the electrolytics have reformed okay and are fine. I am grateful the previous owner did not power up the set.

I today removed the components from the neck of the 21AXP22A for cleaning and examination. After reading the previous posts about disintegrating yoke covers, I was expecting the worst. Somehow the yoke on my set survived. I simply removed the yoke, cleaned off the dust and wiped it over with a damp cloth and found no problem with it. Curious why this one has survived and others I have seen are totally shot.
