Thank you very much for your help.

Hi all, does anyone have a hi-def scan of the PV10a schematic? The one that's available in the zip file is a bit fuzzy!

Anyone got a schematic for ART preamplifier?

Hello! My name is George and I am a new user.
My old Sonographe SA-400 by Conrad Johndon needs to be repaired. Can someone help me with the service manual?
Thank you!

Hi George,
Welcome to CJO. There are no "service manuals" for CJ equipment. If we have the schematics in our database, you can download it from the first post on this topic. If it's not listed, we don't have it. You can also make a new topic to discuss what issue you are having and perhaps our members can help you out with the problem.

Hi,
I'm a new member and have to be honest I am looking for a schematic to repair a customer's PV9 preamp, but can't find it listed in the schematics zip file (or more likely I'm doing something wrong!), if you could help that would be great , Many Thanks Dave, Classic Valve Amps

First, welcome to CJO. Great to have you with us.

It should be there. If you download the zip file as indicated in the instructions in the first post here, there is a directory labeled "PV9 and PV9A" in the zip file. I would just extract the entire zip file and then go in manually to that sub directory.

Hi Roberto,
Welcome to CJO.

I just checked and it seems to be working. Did you follow the directions exactly as indicated in the first post. The link in the text file needs to be copied/pasted into your web browser exactly. On the top right hand side will be a download icon and you can download the entire zip file via that icon. Then just decompress all the files on your local computer.

It's in there listed under the "PV9 and PV9A" subfolder. Are you seeing all the other folders and files?
