I am not sure about what voltage the capacitors are ment for in the amplifier and powersupply. The only thing I have found is the 3300uF capacitor in the powersupply is 25v or more and the 2200uF 15/16v.
If a capacitor is not listed in the schematics with a + or a - is it not polarized then? Am I supposed to use some specific capacitors(besides from not polarized if it doesnt say so)? Only polystryrol and polypropylene capacitors(?).
I am doing this as a school project(well, sort of anyway) and I am planning on doing the etching myself but are people putting these drawing for the etching on the internett? That would really make it alot easier for me.
The only potentiometer I found that was up to 10k came with a small knob. It wasnt big enough in hight or lenght. Can I increase this in a simple way(any tricks? just glue a bolt on and use a better cap on the end?).
And the 0.22 Ohm. Is that for real? Is it really that small or am I misreading something?
I am not sure about which transformer I am supposed to use.
Will this do just fine

Or do I have to use something like this(I don't even know if this will work. I just saw 'audiotransformer').

This one is 30VA which is way over what I need but does that actually matter(safety and soundwise)?

The first one is cheap(like, 30 - 40 dollars), the second one is around 500 dollars and the last one about 200 dollars.
Does anybody have any tips or changes I can take advantage of, please let me know.
BTW. I am talking about the Corda HA-1 MKII amp.
