My first attempt at solid state amplification was Nelson Pass' Penultimate Zen, a.k.a. ZenV4.
ZenV4 proved trickier to build than the simple schematic suggested. I used a chassis from designbuildlisten and PCBs made with the gerbers then posted on passdiy.com. For my first take, I used the electrolytic capacitors that were easily available and some electrical tape 🤦. The sound was disappointing, so I made a number of revisions to my build, to be posted separately.
