"International" capacitors

sounds kinda like you have the relevant info already.

NT

Unless you are looking for "exact" mechanical replacements which may be next to impossible and new electrolytic capacitors of the same Uf and voltage rating will work perfectly and they will probably be much smaller that the older originals. The values that you mentioned are not that hard to find but you while the 450 V voltage rating may be common you may have to sub a

What exactly do you want to know ? The name rings no bells with me. That company may either have gone bust or merged with another.

Are you one of those clowns who think that PSU caps have to be so authentic as to come from the same batch lest the sound of the guitar will change ?

I asked this question because the International caps perform, sound and feel much better than Mallory and Sprague Atom in a Fender Blackface Twin, I dont know why. Printed on the caps : HTD : High Temperature Dynamics( for high temperature) Could this affect the feel and sound in a Fender Twin amp? Thanks Peter.

No Graham, i am not that type of clown.

This is one of those things audiophools will argue endlessly on. Really so long as the rating is correct there should be no difference at all between one capacitor and another. "High Temperature Dynamics" sounds like meaningless marketing speak.

Have you tried Mallory and Sprague caps yourself? They're well known brands with a quality product that should perform as well as anything, I'm curious as to how they sound or "feel" inferior.

all capaciters are internationel. they don' make capaceters in the united states.

Its easy to form these opinions from listening tests, but it doesnt make it reality. Get a couple people to run a double blind test for you and you'll not be able to tell which is which.

pk: BS ALERT: The electrolytic cap values you mentioned are most likely B

• Filter Caps and are absolutely not involved in audio stage coupling functions where someone "may" have a very very small argument regarding types of caps affecting the objective (not measureable) sound quality. Take Sofie's advice and just replace them and no one will know the difference except you of course.... and you will continue to think that the sound is not what it should be. This is a mental thing.... get a grip and get over it. I bet you also believe that your interconnecting cables and speaker wires have to be bi-radially wound, oxygen free copper, 06 guage with gold connectors @ per foot.... and on a blind A/B test you could not tell the difference if someone substitued cheapo cables and wire on typical length cable runs. electricitym

pk: I wish I had the "international caps" you are looking for.... I could make some real money here.

"stiffer feel" read between the lines...... "snake oil" electricitym

Huh? The whole point of a filter capacitor is to "stiffen" the power supply, filtering out the ripple. If you want a less effective capacitor, put a resistor in series with it. I think the difference is all mental though.

In order for there to be a difference, audible or otherwise, you'd have to provide a meaningful explanation of why one company's microfarads behave differently to another company's microfarads !

And *then* additionally why the caps in the power supply would be audible in the sound. It's not as if they're in the direct signal path !

Have you actually considered measuring their value ? I wouldn't mind betting that the caps you're saying sound better have actually dried out and their value is a fraction of the value printed on the can. That *would* affect the amplifier's dynamics. You could mimic that effect by using new caps of lower value than original.

Graham

I suggest you address yourself to the issue of this 'better sound and feel' and what exactly you mean by it.

I'd almost put money on those International caps being a fraction of their original value. This is what happens to electrolytics over time. By replacing them you're restoring the amplifier to original condition and you no longer like that sound.

I can assure you that 'back in the days' when your amp was designed, no-one believed in capacitors having any special sonic effects so you can be sure they weren't chosen for that reason.

Do you have a capacitance meter ?

Graham

I'll bet you that the original caps have lost value through ageing.

Graham

Exactly.

I've been dealing with this issue only this week. There was a guy who was convinced that his guitar amps only hummed in this particular recording studio. We measured everything inside out but he wasn't happy so we took the amp to another location where it measured exactly the same again.

It sounded different of course due to the changed acoustics. Apparently My Guitar Tech can't understand that.

Graham

Now you've proven yourself to be barking mad. Do please explain how the capacitors make it difficult to play !

Look, have a good night's sleep and start again.

Graham

Yes.

Agreed.

It's entirely possible that the new caps actually measure the originally required

That will affect how the amp's dynamics sound when they are replaced by ones of the 'correct' value.

The OP could try say 47uF or 22uF in place of the 80uF to see how it sounds. This will introduce a danger of the amp 'motorboating' though.
