Some in-process pics.  Substituted 450V Nichicon KX 'Standard Audio' electrolytics in the PSU. They are bigger than the stock caps, and so I added a terminal strip.

Substituting a British phone jack, made by Cliff, for the Neutrik stock jack. Looks like this one has better quality contacts. See http://www.cliffuk.co.uk/products/jacksockets/index.htm

For $27 or so, the PEC pot looks pretty good.

Substituted Belden 8450 2-wire solid core shielded (as used in the Stereomour) for the 3-wire braid, and grounded the drain wire at the pot (the load), per PB.   8)

I dig the white plastic headphone jack, nice find!

On the PEC pot, the bottom 1/4 of the rotation of the pot tends to have an unusual amount of channel imbalance, so I would plan on needing to add some padding resistors once the build is complete.

Just need white shoes and belt to go with it. And a white hat.

Thanks for the tip, Paul!  Any hints on values?

Add some liquid refreshment, and all's right with the world.

Another cheap and cheerful tweak: a Belton octal socket.

This probably wasn't worth the 5 bucks: a glazed ceramic 9-pin socket with gold-plated pins (can't be very thick gold plate for the $3 to $4 extra over the plain old ceramic socket, but what the hell).

It looks nice next to the white phone jack while you're wearing your white shoes, white belt, and white hat.   ;D

Last bit of nonsense for the day:  Cardas CTFA RCAs.

FWIW, I think I like the pcx house-brand (Connex) Tiffany's better. At least the Connex RCAs have nuts on the outside and the inside, so you don't have to go back in and re-tighten the jacks.

A minor extravagance: silver wire (and teflon tubing). Handmade Electronics has this for $1.75/ft.

Using the 24 gauge soft-annealed silver wire for signal wiring, and the 20 ga. silver for grounds. Taking my sweet time, a few small steps a night.
