Build help and troubleshooting => MP566-II Tube microphone preamplifier with HPF => Topic started by: Mischmaschine9000 on November 05, 2026, 07:52:58 AM

I finished building one of my seven mp566-2 kits. All of the kits came with a 100n for c19 instead of a 1u that is written in the parts list. Is that an error or just a new revision?
On the finished unit i get until point 5 in the test protocol, there i get tp5:+15v, tp6: +1.3V
I see no obvious misplaced components or solder bridges. Do you know what this could be?
