The R2r is the circuit at the rear

Looking amazing there!.. Got any details:

Pot/Relay switches?
Amp?
Casing?

 

[adamus]

I used an R2r with remote controlled from BBP off Diyaudio. (diyAudio Forums - New project : R-2R Attenuator With Remote Control V2 - Page 1)

Pedja rogic buffers (Justblair's Audio and Electronics Pages: Building the Pedja Rogic Buffer)

very low noise regulator (large board in the middle) to feed the buffers

Sonicaps for output caps.

case is a modushop.biz

front panel i designed and had done by Shaeffer (Front panel express europe_

Yeah it's curly maple, which I also think is called tiger.

I’m jealous! Wish I knew where to source such exotic wood locally.

BTW, my CTH amp enclosure is nearly done. To those interested in seeing how the case is made, you can see my build from this LINK.

Really nice to see those buffer PCBs alive in the wild. Brilliant looking amplifier well done!

That is an amazing build. The recessed knob is an original and really good looking idea.

Personally I am a fan of recessed knobs (at least that's why a tell my girlfriend, boom boom). How do you find it in practical terms?

Enclosure is made of wood, chassis is poplar and the top is MDF (build here)

Hahaha. The knob works quite well surprisingly, can be turned with one finger from top or just grab/turn it from the front.

Cool, will check them out.

 

[smeggy]

zk, where abouts did you get your CTH tube extender thingy? I need one for mine as I start my chassis.

 

[zkool448]

hey smeggy, got a pair of them from eBay. They're great, no noticeable effect in quality, it was adamus who fed the idea.

 

[apatN]

No way. I keep repeating myself. You are a true artist!

 

[zkool448]

lol, thanks apatN
