1. As far as I remember, there is no inner/outer coil. They are top and bottom. My experience, the smaller coil, I think, the lower, usually goes.
2. No, Philco transformers, especially interstagfe and output, go quite often.
3. No. Unless they are paper caps, 110pF stay. Do not touch mica caps.
4. Not fussy. 20% is ok.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
