Default Re: Racal 9081 SSG No FM but he meter reads OK

Hi both

Many thanks for the files and information, I might have to do some more reading of the manual as the PDF marked as old is what i have in the book and assummed it was the newer one from what is said on the diagram.

Do you have the PCB layout as that will make it clear as the board has a different shape. The one with the cut out i thought was the newer one and and the one without the cut out is the older one.

Also the newer one has the relay on that side panel next to the FM loop board.

Started work on the second 9081 and so far working through short caps, one on the 24v, then one on the 12v rail, it powered up then after a short while the 12v rail went down again so another shorted cap to look for.

Many thanks for both of your input

Regards

Mark
