Correct orientation and transistor type for Q3y position
If only my build time was as fast as your response time.
P.S. Notice that if your own LED strings don't exactly reach the total forward drop voltages quoted in the instructions its not a problem, you just want them strings total voltages fairly well matched between the channels. Since the rest are already done and installed in in your case except D1x just match two reds for D1x to complete the PSU circuits.
Hi Nick
I put the Phono in a carton box with adequate ventilation just to simulate the aluminum box will be in the near future so to adjust the TP1-TP1 bias
I see that even in the box the bias is raised slowly but in a continuous way up to maybe over 4Volts, and some time i do have to re-adjust VR2x to the limit and still can't go lower enough to 3.6V, I also use VR1 to lower the voltage but still raise slowly but continuous.
From cold start I see that it may takes an hour or more to reach 3.5-3.6V (without re- adjustement from previous session it starts cold from 1V or less and gradually raise to 2-3V in a hour or so).
I wonder if I put a plastic cover over the two K369s to isolate them (in a way) from the enviroment which is getting warm from the Power Supply Heat
Any ideas?

Its fine. Even more +/- TP1-TP2 DCV allowance between cold start and well warmed up would not be disastrous.
Circuit Description
Hi Salas, Is there a circuit description for the FSP like the DCG3 thread post #47?
I’ve been trying to better understand how this circuit works. I’m loving this project and very happy I’m finally getting back into the hobby.
Many thanks as always, for all your knowledge and support
Ps: I’m slowly getting through the 1600 + pages of this thread.
