Ultra Fi Basic Data Only USB Cable

Here's a data only (D+, D-, and GND)(No Vbus) custom USB cable. It is one meter in length. The fellow that ordered it never followed through. So, if your USB DAC doesn't need Vbus and you want to eliminate the nasty noise associated with running computer power through your USB cable then, this is the cable for you. I charge $350 for this cable on a custom order basis only normally but since the buyer never showed up - it is yours for $125 including shipping on the CONUS.

Chadd's been at it again.  Now he's using a pair of SuperWhamodynes with slot loaded open baffle woofers for his second TV setup.

There are so many good DACs these days...

Here's one I did with an async USB receiver based on the XMOS micro controller and the PCM5102A.  It is 32 bit and 384kHz capable.

Message In A Bottle - SE 6V6 Stereo Amp

The other day while cleaning up the workshop, I happened upon a power transformer from an earlier Darling build, a old DAC-41 chassis, and a pair of 6V6s. What to do...I hate to admit it; but, I'm into repurposing lately.

Searching through my parts bins, I quickly gathered a pairs of RCAs jacks and binding posts, an IEC socket, some 7 pin miniature tube sockets together with a pair of 8532s, a couple octal tube sockets, a couple B+ capacitors, and a pair of Dueland Alexander coupling caps. Add a pair of budget output transformers, that just so happen to fit in the chassis, and I had all the major components of a little desktop amp.

So, I jumped on line and order the balance of what I needed to complete the build from Digikey. Following is the result, a little bit of a tight build; but, a message in a bottle, if you will, in a chassis just over 6" squared.
