Bobo,

Is that from a toe kick heater? (under cabinet?) I've installed quite a few of those, and yes they are silent.

I got them from a flea market. I have been told they come from big computers.
I run them at half their rated voltage.

Most supply caps have snap in lugs, for print boards

But I want to use copper wire

So I thought about using this wirewrap method, which should make the connection better and more solid
It will still be soldered

Should work fine, it looks similar to how the caps are wired in my antique Hafler DH200.

Tinitus, very good, but overkill. Solder is likely sufficient.

You click on the image, it gets larger... folks...

...but he is using a wire tie, like is done with heavy gauge AC wire on electric poles when tied to insulators (just a smaller scale).

On my Parallel caps I did it like this, because of the nice color contrast with the copper wire and brass bolts on caps, how ever doesn't always make good contact maybe didn't get all the enamel off the wire or not a good way ?.

Another thing

Looking at Panasonic supply caps I find that there are some nice ones with higher capacity and low ESR like say 20milli ohm

But some of them have much higher ESR, even in the same range and quality
Maybe they are designed for different application

I wonder if all builders are aware of that
I reckon the higher ESR could result in caps getting quite warm, or ?

Ive used in parallel 11 Mallory 6400 uF 60 vot 45x80mm they not quite fitting for this circuit but they give a nice tone and detail etc to the amp in front of them i have 4 10.000 in serial with ov to earth on them. small caps I suspect have better ESR but using what i had still have 30 6400uF if any one what some ?
NOS. I cant even use them for door stoppers they just roll away.
