These schematic links posted here will be tremendously useful! I think the thing to do is look at the tech data and check the existing components for clues as to what may have been going on. Oh, and my box lid does have shellac looking stuff around it, but the interior bottom looks more dirty, oily, waxy......

No problems! Glad to help whenever I'm able to. I went ahead and tossed up the complete operation manual if you or anyone else needs it. I also dug out the best datasheet for the 1V or IV (eye-vee) rectifier tube. It mentions a value of anything 40µF or more needing special design in terms of inrush current limiting. However if you use 10µF caps like most of us are, that's only 10µF directly on the plate, the other 10µF has ~20K ohms in series with it, nothing to worry about there... Drip some ethanol (aka denatured alcohol, not rubbing alcohol though...) on the stain, then daub it with a paper towel after 30 seconds or so. If your paper towel looks like you just wiped up a spill of cola then that's all shellac, and unlikely to be transformer wax... (Ethanol usually won't touch any of the waxes used for potting, it will however pick up carnauba wax to some extent...) |

Everything on my unit works. Some bridge readings are dead on, then one will be too far off. Nothing is getting hot, but I know the tranny would have been hot quick on the filter caps I yanked with corrosion weeping out of the ends. Basically, I just don't like hearing my transformer to this degree. Are some 30s-40s transformers just louder in general? I wonder because my little Heathkit C2 also is quite noisy. The C3s I have are almost silent. I'm sure that wax in old transformers was in part to provide sound deadening properties & if it's gone perhaps you have what I have described. I'm just sharing and gathering thoughts before I break out my Simpson 260 for current checks.
