Re: Turned the oven on for 1st time - Fireworks!
I found an old aluminum street sign at the salvage yard I was cutting up for heat sinks until I found some scrap 2" copper pipe. I slit the pipe lengthwise and flattened it out. Copper is best (unless you can find silver) but 1/8" aluminum sheet works well. Be sure to use a thermal compound under the SSR. Or like BF, use computer processor heat sinks--They're more compact and most have a fan.
