Philco 41-788 'Tropic'
#18

Almost through recapping - but ran into a scary problem.... There are two .003uF caps (1200v) running from the plates of the 80 to ground. All I had available were 2 NOS ceramic disc caps - .003 uF @ 1KV. I subbed these in and I tried the radio... almost immediately I smelled something and one plate of the 80 got cherry red.... I turned it off pronto. Fortunately the transformer survived (but the 80 filament opened up!!!). The smell was coming from one of the ceramic discs which was slightly blackened. I checked it with my meter and it was a dead short!!! I took these out and the radio played fine. My question - what do I replace these with??? Is there a safety cap that will work??? Do I really need caps there anyway??? The shorted NOS cap has me gun shy using ceramic discs now...
