I am looking for International capacitors info,
On the cap is written: Japan, International, C.
They might be vintage
They came with a Fenter amp from the USA
80 Uf 450 volts
20 Uf 450 volts
I have pics of them.

sounds kinda like you have the relevant info already.

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
22 Uf for the 20 Uf unit and possibly an 82 Uf or even a 100 Uf for the 80
Uf unit.... should not be any kind of a problem with the sub values since
most electrolytics have a fairly wide tolerance rating.

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.

Could this affect the feel and sound in a Fender Twin amp?

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.

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.

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.

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 ?

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

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.

It's entirely possible that the new caps actually measure the originally required
80uF whilst the old ones may be as little as 20uF due to ageing (mainly drying
out).

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.

Buy any old cap and just put a new antique label on it ! That's what happens.

the like sell for up to £20 ea !

And of course you need them for the original sound. ;~)

I simply can play more easy with those( international) more modern?)

The sound respond(projection) is better too.

They were typical japanese electrolytics of their day, and the quality
and construction changed over the years. I would compare the ESR of those
parts to newer capacitors. They probably used a thicker insulation to hold
more electrolyte, so it didn't evaporate as fast. Standard Electrolytics
were 65 degrees Centigrade, today you can get 85, 105, and I beleve 125
degree parts. The specifications on newere electrolytics is much tighter,
they are made in smaller pacakges which mean thinner insulating layers, and
some early Electrolytics only had a connection where the wire entered the
cap, so there was also some inductance in the component.


I don't ever rember seing any datasheets on their parts, just a few US
parts houses selling them for repair work.

It was a brand name of imported repair parts from Japanese and other
countries sold in the US in the '60s and '70s. Tubes, capacitors,
resistors and i think they had some connectors in their product line.
They were about half the price of American made parts and some shops
used as much of their stuff as they could to maximize their profits.
Other shops stuck to American made parts, or OEM for repairs.

Yes, America still makes capacitors, but only the higher grades for
industrial and military applications.

The capacitance value usually stays pretty close, what happens is the
ESR increases, so a smaller value cap won't do it, but a resistor in
series will.
