[sdiy] "VINTAGE AUDIO" capacitors

[George Mattson]

LOL.

I don't know how people have the balls to pull that stuff off.

When I learned electronics, we were making our own capacitors out of jars,
wood rocks, paper using tin foil. We didn't have pure aluminum wrap
available back then. :)

But, we made coils out of toilet paper rolls, oatmeal boxes, wooden dowels. 

The good old days. At least we didn't stael the BBQ charcoal to make
resistors...

You also have to keep in mind that Hi-Fi audio back then really sucked
compared to newer technology. Wider spectrum reproduction and just plain
flat better speakers. And, they came up with TWO of them...Oh, wow. Heaven
was realized in that new fangled stereo concept. Once they quit pressing
vinyl, we finally had a good bottom end without eating up 15 minutes of
available real estate to do it.

original capacitors are based on the same material used in the Phillips caps
in the 60's. They are based on a polyester (Mylar) and aluminum foil. Most
capacitors today are a metallized polyester. They vacuum impregnate the
Mylar with an aluminum spray. They do not have the same AC pulse response as
the true film and foil caps and you can plainly hear it.

Bah!!! Polyester and aluminum foil.  What does he know.

You want to use the "Leyden" brand - GLASS and FOIL

Those, and only those will give a vintage sound.

Sorry, but they don't come in orange or mustard yellow.
