Here's some quick pictures of the construction of a custom 2A3 monoblock build.

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.
