Hi i luvmusic2,
Congratulations! Looks really neat! Now, I have the LD MKIII, so it is not exactly the same setup. If somebody can vouch for the safety of my MKIII amp I would definitively try it.
The BIG question: How does it sound? Is there a real improvement?
Next: Your voltage regulator looks the same as mine. I am not able to adjust the LED readout to read 6.3V. The closest I get is 6.27V. However, it seems that the LED readout is stepped, because I get 6.27V and next 6.43V. However, you can still turn the set screw within the 6.27V readout and see different voltages as measured at the output terminals on the voltage regulator. After a little fiddling and measuring with my multimeter, I can get a steady 6.30V. Sometimes the voltage fluctuates as measured, but minimally (6.29 - 6.31V) - not that it should matter much.
