So the "lab" is a bit quite eh? Well I have been busy with my Black Swan Project, a very superior phono preamp, here is a picture Fred supervising my testing of a proto-board..
Here is the Swan, ugly but amazing, Let's me completely adjust the loading on the cartridge to set up its timbre by ear. I just did an upgrade eliminating any aluminum electrolytic from the audio chain, now there is only one Mylar film in each channel to cut off stuff below 3 Hz (turntable noise and record warping) and added one of those new Aluminum Polymer caps in the output stage for DC Blocking
\
For all those that like tech-shots here is the distortion. the peak is a 125 micro-volt input at 1 kHz with a 1.2 VRMS output with 83 dB of gain, the first peak is that funny stuff that happens when the spectrum analyzer ( HP3580A) passed through zero Hz up through the bandwidth of the filter used for measurement resolution which was 100 Hz. Sorry about the blurries, this is just out of my lab notes and the board was out of a chassis. Second harmonic is 66 dB down and the third is 70, that's at 83 dB gain, you do the math. What matters most is the sound of it, the guys who have been critiquing me for the last couple of years love its space and detail. I will have a couple of lab prototypes out circulating in a month or so for more criticism. Being able to change the loading on the cartridge has impressive effects on the mechanical issues of the cartridge's timbre, you have to hear that to understand it.
I will send along pictures of my headphone amp, also remarkable, in a week or so, no feedback, all current mode gain, quite remarkable.
No, this stuff is not for sale, this is my art and not yet a business.

That's a sweet setup! Well thought out and very ergonomic.
Posting recent-ish photos? Why not, I'm in!
There are many more but they're still on my camera's SD card and waiting to be developed.
