I considered this but it is a "proto-type" and I just used what I have.......
Then I also noticed that Nelson Pass used "white" screws for the X0.......and then I thought.......then I can also 😉

The Toroidy transformer is rather large considered that it is only 20 VA. So I gave up using the baseplate. It was also a bit on the "short side" for the PCB.
The idea was to place the transformer as far away from the Cinemags as possible. The "phase" is marked with some flex. The 2 x 18 VAC is red-red and pink-pink. I plan to use one of the red-pink pairs (in picture) as the CT at PCB. Then we will see......
As I need to make the transformer wires much shorter I will need to keep the "phase information" 😉

I had many considerations regarding placement and the routing of the secondary / primary wires to PCB and to the IEC. I ended up with the solution shows as a ok compromise. Will see how it goes. The front plate will be at the far end in picture and back panel at the front which will give quite short wires for input/output.
