I'd like to put new power capacitors in my old 50's 5 watt Rickenbacker amp. The circuit has 2 identical value caps one of which is axial. The other is in a can that is soldered to the chassis. I've never messed with these cans before and I'm wondering if I have to unsolder it from the chassis. It appears to be radial with tab ends. My solder pencil won't do the job. If I did remove the can does the cap just come out, or are the can and a cap a single unit? Thanks.

How about this. is the can a single section cap? That is just one solder lug in the center, plus the can tabs around the rim? I suggest you take the wire off the lug, follow it to where it came from, then solder an axial cap to that point and the ground at the old cap.
Today's modern cap is going to be LOT smaller than the priginal, and there should be plenty of room to stick it in the works. leave the disconnected can for appearances.Education is what you're left with after you have forgotten what you have learned. -
Recapping the recap
Enzo, What you say makes good sense if I can't do it the original way. The amp works as is and settles down after a few minutes. So I might just leave it alone. The can cap has 2 tabs coming out the top. I would guess the purpose of the can was to shield the cap. The circuit is similar to a champ amp 6V6. Any old timers out there know anything about this???Comment

The can is probably the negative terminal. There is no need for shielding around filter caps.
Look on the side of the can. Does it list the value twice? Is there a little triangle, square, or half moon symbol next to one of them? Often as not it says "Can Negative" right on the can.
It would be very unusual for one ot the solder lugs to be the ground, but possible.. Ohm it out, is either lug grounded?Education is what you're left with after you have forgotten what you have learned.Comment
