WOBT - June 12, 2021: Well not exactly a bench, but this is what’s on my desk. CAD production drawings for a new product that needs review - a hybrid tube/SS headphone amp I have developed with Jhofland in collaboration with Living Sounds Audio. It’s going to be quite a head turner I think. The HyperDrive-2 will have 3 selectable inputs, a preamp output, a tube buffer stage, fully protected outputs and anti thump logic control via a microcontroller for graceful power up and shutdown. It will drive 2w into 32ohms and make clean, engaging and transparent sound, and will come encased in a beautiful custom thick, aluminum powder coated chassis. This is a preliminary render - a few cosmetic details still need to be worked out (upside down volume dial):

Agree, nice work Anand

I had a bit of time myself to sling a little solder Sunday afternoon on my bench. This is the LuFo amplifier verification build. Once I receive the IMS adapter’s loaded with LU1014D’s I can proceed.

Vunce,

Great soldering and great photo! Did you take it outside where there is plenty of light?

Best,
Anand.

I should have noticed the tiny little corners on top showing a weathered wood picnic bench in your back yard. That does look like bright cloudy weather lighting though. We were both right!
