µTracer 3+ build 8

Part 8. grid bias circuit construction

Part 8. grid bias circuit testing and calibration

measuring -12.64 Volt regardless of Calibration slider after making one mistake
I put D21 (HER108) in the spot of D12
during step C9 I found out (because I had 2 more items left instead of 1)

I unsoldered HER108 and put in D21 and then put the correct 1N5934 in D12
