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

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

I just discovered those old Bulgin plugs and sockets used on Marshall Amps and
the like sell for up to £20 ea !

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

Thank you for your reaction,I understand your reply.I am not into fancy
hi-fi gear, that won t work for a Fender guitaramp
I have been an professional jazz and latinplayer over the past 30 years,
playing virtuoso.
I simply can play more easy with those( international) more modern?)
capacitors than with the Atom Spragues and old Mallory s,
The sound respond(projection) is better too.

Thanks Graham , I will try the lower values.

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.

Hi Mike thanks for your reaction.
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.


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.

The capacitance may decrease too.

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.
Thank you Peter Kluken

It doesn't matter who made the capacitor, all capacitors do one thing,
that is capacit.

You are a fucking moron.

I hope you are found dead on Christmas morning down a chimney dressed
up as Santa.
