It's those compact florescent light bulbs. I took a dead one apart, and found 2 15μF 250V 105C caps, and 4 1N4007 diodes. And a few assorted resistors. Yes, these caps can lead a hard life, so test them before using them in a rradio. But this particular bulb appears to have had an open filament, which would make it dead. And these caps tested fine. As well as the diodes. In Australia you'll probably have higher voltage caps than here in the USA, as your mains are 240 vs my 120VAC. Here they sell for a couple dollars, and it might be reasonable to get a few just to tear apart for the caps (you know how it goes, you're restoring a radio and don't have the caps like the ones I found. And you don't want to wait on mail order).
