They are pretty big, this box is about 8" long. I thought I had the wrong order when they first arrived!

I spoke with Campbell at SD and he said that Morgan found significant improvement with the added leads when using multiple stages. I havn't had the chance to use them or compare them yet but I look forward to.

Strange creatures....

In terms of electrical connections, this is outlined in great detail in Valve Amplifiers, 4th edition. Basically, it's a Kelvin connection, one set of leads go to the supply, another set go to the load- they connect right at the cap foils, reducing the effect of ESR from the leads on coupling of ripple and signal between stages.

Wasn't there a t-cap or something from Jensen with more than the obvious amount of connections? I'm talking 2004 or about.

After seeing pg 374 (courtesy of google books preview) I understand how a single 4 lead kelvin cap would work. For 4 stages I have trouble imagining where the 10 leads would go because the basic premise is 4 leads per cap which (after consulting with my fingers and toes) would yield 16 leads if I were to assume 4 capacitors (because of 2x2 stage/channel) and extrapolate from what I currently understand.

Does it look like this? Please say yes because I feel like I just solved a crossword puzzle.

That's the idea for the ten leg but with resistors on both ends and the lead inductance added . So you did solve the cross cap puzzle.

The picture is of 8 leads . I am mising some here . Looked at page 374 in the book and am confused as to 4 leads on each end. Thanks for the insight .
