I traced all the way through it and did not find any errors. Good Work.

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

They way he has it works better

Thanks a lot Heisthl,

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.

Hi Henk<

Looks nice! What's the choice of your transformer?

Thanks a lot Erwin,

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.

Very nice work thank you for this.

I haven't done PCB building for years but this I may try.
