Thank you.
You would almost think I knew what I was doing...

My second built, a cMoyBB. Have been trying several opamps.
I know is a simple build but this is my second DIY and has taught me soldering skills and how to read a diagram.
Waiting for the Meier crossfeed parts, and after that, eSXtatA SS

I originally posted pics of this amp way back in May last year, but I've finally got around to finalising a few changes yesterday, and couldn't resist taking new photos with my new camera......

σ11 is at 27V with a 30VA toroid. Filtered, double-fused, DPDT switched IEC inlet. Amphenol umbilical connectors. Neutrik RCA and headphone jacks. MMM has AD8610 all round, biased to 4.5mA. Output stage biased to 100-105mA. All electrolytics are Nichicon UHE/UPW. Pot on the left is configured as variable gain (2-12), but is currently shunted out of the circuit as I never use higher than 2 with my phones. Teflon SPC input wire, bog-standard copper hookup elsewhere.

And it is finally exactly how I want it

Yay ~ Another CMoy!
 

 
My first(ish) crack at one, my initial board had a problem with distortion in the left channel so failing to fix it I made another.
 
Case is a small Hammond that I've cut to length (I could have made it a bit shorter) with panels made with wood I happened to find on the side of the road.
 

 
~Please excuse the horrible picture quailty~
 

 
My first attempt was a lot neater underneath.

~ Starving Student 12AU7 ~
 

 
My second go at a Starving Student (first being the Beezar PCB kit)
 

 
I've used Ohmite carbon composite resistors, Vishay axial electrolytic and TAD "mustard" caps as well as a pair of JJ Valves.
 
I used star grounding as opposed to soldering the grounds to a plate.
