I have read throughout forums that using ammonia to clean coils to neutralize the acid from the plastic breaking down is a good idea before rewinding.
However I have also read that ammonia removes varnish, which is what the wire is coated with.
I can attest that ammonia will indeed remove varnish from coils.
So the big questions are is the ammonia to be diluted, what ratio, and how long of an application ?
OR is there a better alternative to remove the risk from eating the varnish away and still neutralizing the acidic surface ?
Also while we are on this subject, on Philco 70, 90 the primary is 32 awg.
Has anyone rewound the secondary and what gage did you use ? Were you successful ?
