I've put some more detailed pics of the PCB on my site
(http://nixie.ramdac.be) board2.gif & board3.gif
Maybe someone has an idea what those cryptic markings mean on the
jumper field... I suppose the C-field is not adjustable electrically
(not on connector), but where could it be adjusted? There is a hole in
the physics package with some adjustment (C?, R?). I think it is R118,
the big blue multiturn pot. For the rest I only recognize the 10(?)MHz
oscillator & multiplier (60 MHz) on the top of the image.
All remarks/suggestions welcome.
73's de Jacques.
