PS re-cap

[STEEDA]

Came across a board today which has two 4700uF / 50V Lytics and I noticed that I had to desolder THREE leads (per cap) instead of two! My best guess is that one of the lugs serves as a "support" so the Caps cannot bend on the board.

Any "other" ideas? I don't remember seeing a 3 lead cap before this BUT then again, this IS an old board, so that could be why!

Thanks

There are probably two caps in each with a common ground. Those are not that uncommon.

I just noticed this as well while replacing caps in an old pre-amp. I noticed there were 3 leads instead of the (usual) two!

Good to know!

dual caps

If the cap truly is a dual style it will have a value similar to 4700/4700 @50 volts. If there is only a single value listed then the 3rd pin is a support pin. Very common on PCB mounted large size caps.
