I've always used Orange Drop.
Never a problem and I can always find some quick if I need one, or two, or several. _________________ I have stuff.
I try to make music with it.
Sometimes it works.
Sometimes it doesn't.
But I keep on trying.

If two .022 mfd capacitors sound different, then at least one of them is not a .022 mfd capacitor. |

LOL, +1 for "EB". I'm an ex amp tech and have worked in Electronics for many years but I'm not an "Audiophile" so I'm not attuned to how or supposedly how they sound. There are some that are better tolerance or tend to last longer. _________________ GFI Ultra Keyless S-10 with pad (Black of course) TB202 amp, Hilton VP, Steelers Choice sidekick seat, SIT Strings

Not all orange drops sound alike. Some use mylar (polyester film) and some use polypropylene. Some use metal foil, some use metallized film. Then the different styles are made a bit differently, their geometries vary, their tones vary.
Orange drops I've met:
715p
716p
418p
6PS
225p

That is so true Brad. I am personally not a fan of Orange Drops in Fender type amps and I have built and repaired many. They are very HiFi sounding. I do however like Orange Drops in hifi amps.
It's hard to go wrong with Mallory 150s really. The old Blue Mallorys or Ajax caps found in blackface fenders are great and RARELY go bad. I test leakage and measure ESR in all coupling caps that come through the shop and I have only found a few that were leaking DC. I have used Jupiters too but the blind fold test proved they sounded no different than Mallory 150s but cost way more.
My 2 Cents

You might want to see if this cap fits your price range and the space inside your cabinet:

For the price those caps are absolutely phenomenal sounding. |

Yup, MR's could be overkill if the speakers are not high resolution models. Even the Clarity SA and PX series caps are probably an upgrade to any of the above listed caps. But they are large too... |

Please translate. I've read that article three times now, and I still can't understand what he is trying to say. Here is the quote from the paper:
"If an amplifier is "capped" by taking all electrolytic capacitors out of the signal path, and replacing them with good film capacitors, it has to sound better. All the experts say it sounds better.Tom Nousaine....... says the golden-ears cannot hear a difference, in truly blind tests. I believe him. Of course, that does not mean that there are no differences. But it's well-known that tantalum caps can sound pretty weird if they are ever allowed to get biased the wrong way during part of a cycle. I bet even I can hear that kind of distortion." _________________ Emmons & Peavey

Impossible to answer the question without knowing the specific application. There are many types of capacitors and there is not a one-type fits all.

Sorry in advance about my very wordy post.
Stephen - I agree, as I have reread this article a bunch of times. Bob Pease was a big believer in dispelling audio myths. He often called them "floobydust". At the end of the article he even goes off on speaker cables. He was a brilliant electronics engineer (not necessarily a diplomat) and all his articles are chock full of theory and equations.
I believe that tantalum capacitors can clip the signal if it goes into a region where the polarity of the capacitor is reversed. He also may have been talking about the fact that tantalum capacitors can short out and explode when reverse biased. Here is an article about their characteristics. http://www.capacitorguide.com/tantalum-capacitor/
The relevant paragraph is:
"Polarity
Tantalum electrolytic capacitors are exceptionally polarized devices. While aluminum electrolytic capacitors, which are polarized as well, might survive a briefly applied reverse voltage, tantalum capacitors are very sensitive to reverse polarization. If a reverse polarity voltage is applied, the dielectric oxide breaks down, sometimes forming a short circuit. This short circuit may later cause thermal runaway and destruction of the capacitor."
All the different types of cap have different "parasitic" components that go along with capacitance. I think a big player might be the "equivalent series resistance" at audio frequencies.
All that being said, 35 years ago I recapped an old Gibson amp with orange drop caps and I was blown away by the difference in tone. Probably due to making the circuit right again rather than the particular caps. But you can't go wrong with them and I've used them ever since. _________________ Excel D10 8&4, Supro 8, Regal resonator, Peavey Powerslide, homemade lap 12(a work in progress) |

The Bob Pease article really addresses a characteristic of capacitors that has nothing to do with sound quality. In the past decade or so enough research has been done to indicate that it's primarily the physical resonances of a capacitor that give it either poor, adequate or superior sound fidelity. To some extent, a capacitor is affected by changing currents as a piezo transducer is.
Twenty or thirty years ago the technology was generally not up to the task of delivering speakers, cables and other components that produce exceptional sound fidelity. So naturally a person needed to be wary of snake oil salesmen or golden wonder type claims.
Electricity is a very interesting and surprisingly complex thing. How many know that the energy flowing through a current carrying wire does not travel along the wire? It rather flows from outside the wire into it from a 90 degree angle. You can see that from the Poynting vector. That sort of mystery made even J. C. Maxwell's mentor William Thompson think Maxwell's theory was "metaphysics" rather than hard physics. |

The usual drivel.
In guitars there is minimal difference with 99% of capacitors - the value is much more important.
There are a *few* odd ones that cause a slightly different "slope" - the speed with which treble is rolled off. But that's the ONLY difference. Guitar "tone" caps have NO "tone". They are merely a subtractive device (unless in an active circuit). All they do is *remove* frequencies. It's physically/electronically impossible for them to add anything. _________________ No chops, but great tone

Which are the few "odd" ones, Jim? I'd like to check it out. Always up for learning more minutia. _________________ Excel D10 8&4, Supro 8, Regal resonator, Peavey Powerslide, homemade lap 12(a work in progress) |

Hi Jim, We need to remember that subtracting a noisish AC signal is just as destructive to fidelity as adding one, right? |
