I've looked all over Google and can't find a 80000 uF 50v DC capacitor in a 3" diameter can with screw terminals. I need this for a power amplifier repair but can't find one anywhere.
Help locating this capacitor would be much appreciated.

I know very little about electronics. How close to the original specs do the replacements need to be to avoid performance degradation and/or melting the circuit (or worse)?
I'm new to this. So the 75V won't damage anything? I don't know which numbers I can move and which numbers have to stay the same as the original.
The voltage is the maximum that the capacitor can be operated at, so a cap with a higher voltage rating will work perfectly well as a replacement.
Electrolytics usually have a tolerance of -100% to + 200% so the closest similar value will usually work. Don't be tempted to go too high as you may introduce issues with the rectifier.

Cornell Dubilier has the DCMC743U075DC2B, 74,000uF -10%+75%, 75V, 3"x4.125".
It is $87 but looks pretty sweet.
Is the original in really bad shape, IE broken or leaking?
Can you post a picture of the label on the original cap?

Ebay Item number 221427472697, Western Electric 75000uF 60V 3" can with screw terminals, 2pc. $35 from a US seller in PA.
Like White On Rice, I'd jump on it.

The original is long gone. Here's a link to a picture I found online:

Those went years ago and I replaced them with 96000uF 50V units (couldn't find the right replacements then either, but that was before the internet) that required me to cut holes in the bottom of the chassis because they were taller than the originals. I'd like to get back to a size that will go inside the chassis so that I can return the amp to its original look.
What's an IE? The originals started leaking and were replaced years ago. The replacements started leaking recently.
I've had the amp since 1985. I think I replaced the original power supply caps around 1998.
united chemicons made in usa also come in size you looking for I guess, don't know how high you are looking for. digikey sells them, cheaper, and I wonder if they all produce them themselves or are they all from same factory?? well they are blue too🙂 63v
I don't know how historic you want to stay, but back then large caps like that mainly came with screw terminals. But electrically the terminals are not the issue. So you might expand your search to caps with wire leads or caps made to "snap-in" and save some money. Then solder the wires to the cap leads instead of screws. That usually brings a $35-50 cap down to $10.
i.e. = id est = which means "that is" or "in other words"
e.g. = exempli gratia = essentially "for example"
I have to admit I had forgotten the Latin words for e.g. Latin study was high school back about 1962.
