Need replacement cap

[goat67]

Not to go against EWs recommendation but since I shop Mouser not Digikey
only because DigiKey is in the state I live in so I would pay sales tax.

I decided to check Mouser and found more than one screw terminal type
I would have used. It all Depends on what you want to spend.

I would have gone with the last one higher capacitance is a good thing for this application.
But really any one of these would be fine.

Ranged in capacitance from 4300uf to 7000uf voltages 63v or 75v

75-36DX422G075AC2A 4200uf 75v 35mm X 35mm $12.54

598-DCM472U075AH2B 4700uf 75v 35mm X 67mm $15.85

598-DCMX612U63AA2B 6100uf 63v 35mm X 54mm $19.93

598-DCMC63V702 7000uf 63V 35mm X 54mm $17.27

Since you all ready have one on order it does not mater just thought it might help in the future.

Nothing wrong with those suggestions. Mouser has only recently (OK...for the last 18 months or so) stocked those 35mm screw terminal caps, so I don't often consider them. The only advantage is being able to add ring terminals to the existing wiring for easy connection, but it is a nice thing to be able to do, for sure. Thanks for reminding me that they carry them.

WTF is a 'block' electrolytic? Yes, I saw the attachment. I suppose the author is referring to a 'large can electrolytic' as a 'block', as far as I can tell. Large cans are designed to deal with large currents and have an abundant ability to dissipate heat...beyond the capabilities of a standard radial-lead electrolytic (at least on paper).

If this is still about the 3300µf supply cap, my recommendation hasn't changed.

Block is as exactly as vintage Pioneer used to call them, and as the circa photo description in the pdf shows.

Earlier in this help thread, people kept saying just find a 3300uf 63v. Now it is KNOWN that Pioneer called these CE(w) block caps you know as large can.

Yeah, "block" is a weird thing, I think its just a standard electrolytic, since its still uses the "CE" desriptor. Maybe they were trying to differentiate between board mount and chassis mount? . That paper deals specifically with pioneer numbers (very helpful, by the way), so I don't think you'll hear about "blocking" caps anywhere else. As rockmore figured, the cap hes replacing is a CEW, or standard electrolytic with radial leads.

And, good luck getting the right cap...not an easy thing...

Thanks guys- still determining what should be used, not just what can be used.

I would of thought with all the experience and brain power in this forum alone, replacing the standard Pioneer block cap would be a given... but.... 33- youre right, not an easy thing as I would of suspected.

I Plan to fire it up when finished with the Nichison KW in it now, and move from there through testing (and hopefully not any fires...LOL).

Goat- Just FYI- Spoke to Digikey again Monday- they stated they have reps in most states now, foregoing the no-tax loophole. They said if they have a "rep" in a state, they charge you full sales tax now. So.... I got charged full sales tax on my last 4 orders. Not a whole lot, but it adds up. I am not in MN.

What you're discovering is that, since you can't simply dial up the manufacturer for parts for a 35 year-old receiver, is that you have options and decisions have to be made.

A little friendly advice when asking for suggestions on parts substitutions look at the source of the advice given.

If EW or MTF tell me that this is the part they would use I pretty much take it as a fact.
They have much more experience and that is the reason I asked in the first place.

I may then go look up the specs of the part to learn more and then find other possibilities.

But in the end it is up to you to make the final decision.

The cap you have in there will more than likely work but I would
not have even bothered to put it in there as it will just look wrong.

LOL.

I did simply "dial up the manufacturer", on my own, to find the original vintage pdf that shows that Pioneer called what is common, and I needed in this small instance, a block capacitor. There was no correlation between your "large can" cap with the standard Pioneer block capacitors until I found the pdf in a hour elsewhere.

So, future users popping the lids off their vintage amps/receivers wanting or needing to replace them will know what they are, especially what Pioneer calls them, and then hopefully find a decent, current replacement without having to go through a month of "guessing by the experts" because of semantics.

NOW, since these block caps are so common in vintage Pioneer, hopefully a sticky or thread will be created for the best current replacements for them (NOT original Pioneer parts from Elna one made), and also that Pioneer's block cap = current terminology of what you all call "large can".
