Who's afraid of the Big, Bad SVT? 'Cause I Need Help!

Who's afraid of the Big, Bad SVT? 'Cause I Need Help! I'm working on an SVT right now that was blowing fuses because one of the filter caps shorted. I replaced it and it's fine now, but it still pops intermittently, which is what it was doing before it started blowing fuses. Do I need to replace all of the filter caps and tubes before I can be sure of anything? Has someone had similar experiences? I don't think a power tube or socket is arcing, but I can hear a click in the chassis at the same time as the pop in the speaker. It does it without the phase inverter tube in, but it sounds a little different when I do that. When you try to play through it, the popping sucks the signal out for a half second or so. I noticed it will only start popping when it gets hot, so I can't get it to pop when the chassis is out of the cabinet (I thought I might be able to see some arcing.). It pops more when I try to play through it. I checked a whole hell of a lot of other components, and they all seemed fine. What components should I replace just to be on the safe side?
