Re: Cossor 500AC SW oscillator coil failure
Jim,
I believe you are correct on this. At the risk of going off topic, I remember reading some time ago that a transformer company, Woden I think, carried out some research into this in the 1950s as a result of complaints about breakdowns in their transformers. During WWII and for many years afterwards more women were employed in electronics factories as the men were away on service, and apparently during 'certain times of the month' the moisture in their fingertips is very mildly acidic, which over time can eat through thin covered wires. When Woden discovered this they required all their female operatives to wear light cotton gloves when working on winding coils and transformers.
