To Mr. Merlin the

Two V1.0 shunts are better as Ricardo has experienced too, no doubt, but not a restriction, just a little more quality. You can taste 90% of the quality with just one for now. Your channels are very well matched judging by the voltages you measure now that they are finally both running well. That Q6 must have died during experiments with the shunts, if it got more than 47V at a point.

Nothing much about the help, I would just have hated you have spent so much money and left sorting it out alone. I hope you have now some more experience and be more confident trying circuits beyond kits in the future.

Now the next step will be to up-grade the regulator with remote sensing

Workable for now, nice clean build with very good components in general. Of course shorter cables later when with two shunts operating will be better, and then remote sensing of course. How did you kill one tx by the way? If you experience any hum from GND loops, or from the AC cabling running across meanwhile don't pay much attention before you would have the final arrangemend to debug anyway. Have a happy initial listening. Good job.
