Those MKP caps are in good 1% RIAA tolerance to make a build care free and economical. It was not easy to find 1% in those voltages and it was a must of getting many and having an LCR meter for other brands and types in sane prices. They aren't something special to must substitute an already installed trimmed array of other caps was the deal, or am I wrong in that assumption?

100% correct salas.

With the receipt of the SSHV2 board a few weeks ago, I began assembly of my power supply. Tonight I connected all of the pieces and tested it. So far it's perfect. Rock solid voltages at all 3 outputs. The SSHV2 is fantastic. The voltage across the TP points hasn't changed even 0.1 mV since I set it. The B+ voltage hasn't drifted at all, either. Both of the heater voltages are exactly where I set them. This is great.

I got some help on the design of my PCBs from a local EE who I met through AudioKarma. He gave me a lot of good tips, particularly about using lots of copper. I have a few changes I want to make if I ever make another set, but they seem to be working very well so far. I had a few of each made through Silver Circuits, and the build quality is above satisfactory for the price I paid.

I had a custom power transformer made by Edcor. It saves space and looks nice. I've got my chassis cut out and ready to wire. That will be my project this weekend. If everything goes according to plan, I will have music on Sunday.

Well..... I've got the circuit assembled, though I haven't physically put the whole unit together. But it's functional so I can test it.

It doesn't sound that good. The high end is very muted. I've attached a couple of samples. One is from my valve itch, the other is using a Musical Fidelity V-LPS. The turntable is a Dual 1229 (that needs a new idler) with a Shure V-15 III cart with a JICO SAS stylus.

What might be the reason for this? What are some things I can try to fix the lack of clarity?

There's also some hum that I'll have to chase down. I think I've got something grounded wrong.

Are you sure you have the RIAA correct?

Well I checked each R and C against the schematic as I installed them. Most of the resistors I measured on the DVM to be sure. I guess it's possible I missed one. All of the parts I ordered came right off the BOM, so presumably they're all correct.
