Rubicon 1002 thermal runaway

I heard tip102/tip107 can be a problem, something about SOA ratings.

Not sure what the front end board is, a daughter card or part of the crossover?

What do you think of bringing the caps up slowly with a resistor or test light? A best practice or not necessary even with older caps that have sat unused? I figured it can't hurt and think if I didn't I could have popped a cap right then and there.

You can. wouldn't hurt.

He was using TIP's as an example. Those were in the Reference series but same test.

I wouldn't worry about reforming caps unless they were unused for 20+ years. Even then, in a car amp, it's pointless. You could use current limiting (5-10 amps) for a minute or so, if you're concerned.

Side note:

My RD1000/1 I just received has Yuscon and Samxon caps. Those should be pulled immediately, damn Chinese build house.
