Very nice, thanks for sharing. One small observation, I remember from a previous post that the higher voltages should go to the cathode follower

On my Printer "Samsung CLP-610D" Kodak Premium High Gloss Photo Paper works best. Need some more work to peel off. Result is very
sharp edges. Try some other Brands for the best result on your own Laserprinter. I know Epson Premium worked best on a HP 1100 Monochroom Printer and is easy to peel of.

I use prim. 220/230 V - 30mA -> Sec. 220 V - bridged. 6.3V-1A
They are custom made by Jaspers Transformatoren in Maastricht.
I use them in every Preamp 1 to 3 x 12AX7.
kijk in je PM

Thanks for doing this!
I've been sitting with a bag of parts for a D-lator forever and this spurs the project along.

Hi,
thanx a lot!
btw, how must the psu be changed to use a sec. 220V transformer?
hmm, do I see the soldering side? The black pic I mean, cus the green one is the same with the componets on.
