What about the old CDR tubular foil caps I used? How good are they?


Dunno, I'm not familiar with them.


Please do replace the remaining old capacitors, apparently they are
prone to shorting.


Apparently. The next time one shorts, I'll do the rest.


Please do it soon.
Scott already told what can happen when a cap shorts.
A supply rail going down via a foil cap may damage your amp, and take
several other components with it.


I agree. The one cap that burned took out two neighboring film caps, but no
electrolytics or other parts are in the vicinity.


Well, there you have it.
You can never predict what a short will damage before the mains fuse
blows.
