THE CANS CAN BE SINGLE OR MULTI VALUE CAPS. I HIDE THE REPLACEMENTS UNDER THE CHASSIS WHEN POSSIBLE. I WILL NOT RESTUFF A CAN UNLESS ABSOLUTELY NECESSARY. THESE CANS HAVE PCB'S AND OTHER EVIL SHIT IN THEM. IN MANY CASES, YOUR REPLACEMENT CAPS WILL NOT PHYSICALLY FIT IN THE CAN. I LEAVE THE CANS FOR APPEARANCE IN MOST CASES. IN THE CASE OF A PC BOARD CHASSIS, I REMOVE THE CANS AND SOLDER IN THE REPLACEMENTS. IF A CAN GETS HOT (EXCEPTING HEAT TRANSFER FROM THE TUBES) IT'S BAD. IF A CAN GETS HOT, POWER DOWN. TAKE THE CHASSIS OUTSIDE AND LET THE CAN COOL. THERE IS A GOOD CHANCE THE CAN COULD EXPLODE. YOU DON'T WANT THAT TO HAPPEN INSIDE YOUR HOUSE.
THERE IS A CHANCE SOME LYTICS MAY STILL BE GOOD. DON'T RISK IT. REPLACE ALL ELECTROLYTIC CAPS.
