How about a Pass B1, the Hypnotize version, Salas's shunt regulated, direct coupled style.
To answer the most common questions:Why all the copper? A:I wanted to shield the attenuator and circuit board from the transformer and show off the Goldpoint attenuator.
What's with the little circles? A:My DIY attempt at engine turning, I am getting tired of plain face plates. How does it sound? A: I dunno, it is not my gear but I may get to hear it. I built the case and wired it up for a friend. What kind of material is that? A: For the most part, 6061 Aluminum .125 plate. The sides are extruded T-track. The copper is 14 ga., I believe. The top is Lexan over copper. What kind of attenuator is that? A: Goldpoint 20k.
Props to Nelson and Salas for their efforts, I have the simple version of the B1, Pass labs board with matched fets.

Pass X-Ono Phono Stage
Hi All
Here is my contribution, the Pass X-Ono phono stage.
I started work on this approximately 1 ½ years ago, and I thought I would never finish. Too many other hobbies competing for my available funds.
Anyway, I only have a bit more wiring to go, and the installation of the some components.
I am also making a selector board, based on micro relays, to replace the DIP switches, so I can select appropriate cartridge loading from the front panel.
Hence the rotary switches are not connected to anything yet.
Whilst it will not have the fine control of using the internal DIP switches, it will at least allow some front panel control.
All going well, I should be able to complete it and give it its first test this weekend.
Thank you
Regards
George.

Six channels F5 driving my speakers in the night, playing Pink Floyd Wish You Where Here over the Squeezebox classic, and of course, my own DAC
/Edit: the F5's cannot be seen, as they are hidden behind the old Sony TV
An externally hosted image should be here but it was not working when we last tested it.

Finally F3 Re-Boxed
After getting my F5 built, my F3 had to go into the shop for some new, larger heatsinks to better handle the heat loads... Here is the result (yes, another Peter Daniel copy!!):

Jfet Delite with Japanese lantern
Looks great Tony, have you got any photos of inside ?
Cheers Simon

Finally, I finished my F5 in the refurbished (new front- and backplane) Telewatt SA600 enclosure
At least nearby finished: just a LED in the frontpanel is missing.
Inside view:
Actually driving the Fostex FE83E in the bowls on top of my desk, a nearfield setup:
Below the desk, you can recognize the 15" Goodmans bass. The desk is like an open baffle. The Goodmans is driven actually by a bridged LM3886 amp.
On the right side on the desk you can see on a breadboard the miniDSP I am using as crossover (spdif out, followed by my own DAC's).
