looking at this damn set and thinking, well no wonder the damn thing fried, there's one .05 uF capacitor coupling both sides of the AC line!

Digging way back into my dim electronics memory bank, it was (is?) common practice to put a small non-polarized capacitor across the 'line' with the off/on switch to prevent arcing during the make/break cycles and thereby reduce the incidence of carbon buildup on the contacts.
The cap has to have a fairly high VAC rating as the induced instaneous voltage from the spark can be greater than 240 VAC, as I recall.
