What min corrent ? and this?1PC LT1083CP Sliding Type High Power Adjustable Voltage Power Supply Board | eBay
I believe everything should be clear if you read datasheet of xformer
having separate secondaries and connecting them to have CT is much easier that the other way around
here's some help
ignore miss-type here and there
if you have datasheet, post it here

duh
no color info there
what wire colors you have , one secondary, second secondary?
usually, start of winding is one color, end of winding other color
say that you have green and yellow
green 1 : first secondary out (to diode bridge)
yellow 1 + green 2 : Center Tap (GND)
yellow 2 : second secondary out (to diode bridge)
checking is easy , by sketch I uploaded ; connect two wires from different secondaries, put Vac meter across free ends,power up Donut ( taking all safety measures - isolated mains contacts etc.), measure ; if you have double Vac , that's the arrangement ; if you have nearly 0Vac , change place of wires of one secondary, retest

I understand. Thank you.

They are ClarityCap CSA bought at HiFiCollective.
I went ahead and put these caps on the outputs of both my Pearl 2 and BA-3 FE, replacing the electrolytics and film bypass. 2.2 uF is all I need based on input impedances. I listened for a few minutes and my initial impression is positive, I'll try to do a longer session tonight.
Don't laugh at my BA-3, I mistakenly bought components that are oversize and crammed them in.
What os the best regulator?

The first one has no description. The second one would work, I use a similar one: WZ-4 LM317/LM337 Adjustable Regulated Power Supply Board | eBay
