My JLH1969 in an old repurposed CubePC case.

SMPS for power seperated with a suspended aluminium/composite board.

Just waiting on smaller speaker binding posts to finish.

Hi riritronic,
So, how does it sound? Nice, compact build.

Suprisingly, it sounds very good, no buzz, no breath, just an high frequency residue but not audible, just noticeable on scope. I will perform distrotion measurement later.

Hi! Very nice!
How does it compare to SARA?

My Simpelstark+ build is progressing.
Both channels are mounted on the heatsinks and tested with my lab supply.
Running smoothly. Jeff has assembled the control board for me. Need to arrange the mounting frame for it.
Next steps - soldering 2 x PSU boards, then wiring everything.

Don't you know that Coke is bad for you? That looks like a killer bottle for just one person! Spilled Coke makes on heck of a mess too.

Looks like it will be a clean build, as usual for you and Jeff.

Some pictures about my the latest version of my V4 amplifier. Power supply +/-40V, output power is 70W/8ohms, and 120W/4ohms.

Nice work sajti, very nice!

Chris, I knew there will be some comments on that killer bottle 😀
I'm careful enough with it 😉

Sajti, a well-organized build with 2 x PSUs - nice work!

New version protection board by Jeff ideal for a dual mono,very interesting thing.
