Of course! You cannot be really "shure" if you are using a stanton!
Sorry Roy, but it was so funny!
That's my simplistic PSU: 27Vac in, 32Vdc out. Load 200mA from one regulator.
Fiddling with PSU Designer gave the exact value for the resistors, which get luke warm. The inductors filter common mode noise, value is not that critical. For caps I used Rubicon ZLH which have good HF characteristics. The 1200uF might be exchanged for Panasonic or Elna after auditioning.
The ripple is 50mV. This could be reduced but what's more important (it might prove otherwise) is the shape of the ripple which resembles a sinus. Avoid triangular shapes as these are more difficult to filter with the regulator.
Edit: the bridge rectifier in the schematic is 90 degrees rotated. Do not built it this way

Yes, MUR620 (36nS recovery time). Usually I take Schottky 1N5822.
Some say to observe audible differences between diodes. I guess it comes down to more or less ringing and noise from that. But, I'm no expert in this matter 😀

I have order some stuff for phono I will report if the sound good 😉
rifa169 4700mf for rcrc filter with my KG 4700mf
and two new trafo 48VA from hammond 229 series :
split bobbin design,low primary to secondary coupling, balanced windings, no electrostatic shield required and low EMF radiation due to semi-toroidal design.
I hope this work better then small blu talema toroid

An externally hosted image should be here but it was not working when we last tested it.

Oh, yeah, I forgot! Are you into bikes? I got a v-strom (was drooling over a guzzi or ducati but they're out of my price range 😡).
wow
Special tx
I see the pic but can not understand where are you going to use a 10v TX.....
😕
