Hi i will try to take some pics
Hi Alex, thanks and very interesting indeed. But this is way out of my ability
I was thinking to something much more basic. To send to the caps before the regulator (i understand there is just one regulator ?) a DC regulated voltage bypassing the internal toroidal
In this way there will be two stage of regulations. I have already a suitable lab power supply 0-30 V that i could use (adjustable of course on the V needed).
Just a DC socket on the back and some wires will be needed on the unit and the mod will be reversible. The unit could still work with the original PS.
In this way i should be able to lower noise, increase mains filtering, avoid any vibration induced noise
But i have to look at the pcb and measure the DC voltage before the regulator
Please post your pictures
Thanks and regards, gino
I myself would (and will) go for external feeding XO's with ultra low noise psu.
You can order the 0.8uV ultra low noise from DIYINHK, as earlier posted. It is a double version and needs 2 seperate 6~ to 8~ Volt transformer ( transformer 6Vx2 15VA).
....
I will post some pictures when starting this mod.
Cheers
Alex
