I had to try this CLC supply using the exemplary $$$$! Mundorf MLyticHC caps, they are such incredible components. 4 times the cost and 1/2 of the capacitance compared to "the other" CLC supply... I have said it elsewhere / before ~ they are a break-through ~ in performance, in 4 other amps that I have built and tests, using them... We will see.

The Mundorfs are much larger, which required a different chassis layout to fit them and to get the lead lengths of the toroid and the inductors to reach. I wanted to retain the magnetic isolation of prior build, with the transformers in the front of the chassis. I still have 1/3 of the rear of the chassis to place the driver board and heatsinks, that will eventually be used (in place of the "Hafler" power modules.

I wanted a sound comparison of United Chemi Con caps and the Mundorfs to determine while I will use in my final amps design / build. I have included the commentary about various power amp configurations that I have used so far to test these Power Supplies.

I have been starring at the 3rd supply trying to reason how I want to wire it. I am very happy with the UCC capped supply... but there is not way to duplicate it with this layout, everything is different, even with 2 inches of additional (interior) chassis height... I am still somehow a bit cramped.

The massive - fat caps dictated many layout options, working with inductor lead lengths and a tidy ground buss / ground set-up... Still working to figure it out... Mean-while the UCC franken'amp is serving well with the Maggies and I have "a spare" 500 and 600 heat-sink assembly to work on... I am *completely* rebuilding the chassis pans on both amps...
