I have build another one(positive), with random 1N4148 diodes, 1000uF 200mR caps, Q1 BC337-40 PH59 and Q2 FairChild BD-140-16.
Everything is stock(default dummy load ~25mA):
across 3 1N4148 i get
1.7V drop
When working with
29.80V input, across R2(1K) i get
38mV drop.
Output - input voltage differential :
2.04V(takes a ~minute to settle down)
Applieng 160mA load to the output increases voltage drop on R2 to
43mV.
Is everything working correctly ? Going to adapt them soon in preamp psu circuits
