Hi, if you have need of the M12 Ludlum manuals, they are present in the forum where I am moderator: http://www.radioactivityforum.it/forum/ ... f=25&t=197
I hope this can be of help.

Re: Problem with Canberra Series 30
Hi, I did a little test of the instrument, it seems okay.
I put the picture of a pair of spectrum.

Re: Problem with Canberra Series 30
Ok, I solved the problem, I'm just stupid. To give the supply voltage in the safety, at the instrument under test, I use a 230/230 isolation transformer and a variac with which the straight edge voltage, starting from a hundred volts, and if there are no problems the increased up to the operating vo...

This is the link for video: https://www.youtube.com/watch?v=QFi9G9N ... e=youtu.be
the quality is bad, but you see the problem.
I also tried to cool the various components to see if the problem is due to something that works badly or has problems, but nothing changes.

Re: Problem with Canberra Series 30
Further work: I replaced a pair of trimmers and some capacitors. Now the image is in place, however, there is another problem .... the image, as time goes by, begins to have a flicker (especially visible in character, a kind of ripple) which becomes more and more visible.

Re: Problem with Canberra Series 30
Hi Richard, Update: on my unit, power supply ok but no video. I checked and there is a problem in the transistor that drives the high voltage transformer (Q414). I tried to replace it with another PNP that I had (MJ2955). Now picture appears but not sharp and not fill the screen. Of the transistor, ...
