Sorry to hear about what happened. If the fuses are not blown I think you need to open up the 2250 and see if you see anything with visible damage. Unfortunately, the 2250 is not in our database as of this time. If you do get a copy, please send it to me and I will update the database for others. Hope everything works out well.stevieray wrote:Anyone got a schematic for a MF 2250? I looked through the list; I don't think I missed it.
Playing last night, one of the speaker spade lugs twisted around and shorted the R speaker terminals while I was out of the room. It wasn't playing too loud, but no sound. I haven't looked at it today or tried it again. Both fuses on the back are OK -- are more inside? Very, very little sound was coming out of the R speaker -- not silent but just a little. Swapped in another old NAD amp and all works good, so it's definitely the amp. I hope there's something simple inside, but I fear an output transistor is fried. No smell, at least!

Hi Admin,
Most if not all of the CJ manuals can be obtained from the CJ website through the service portal. Direct link to the manuals below:

Conrad johnson just redesigned their website. Clicking on a few of the vintage and current products shows they have user manuals available for download for a lot of their products. Grab them now before they change their mind.

It should be in the "Part 1" zip file. Just download the file and extract the PV9 directory.aiello54 wrote:Anyone got a schematic for pv9? I looked through the list but I didn't find it.

Does anyone have the schematic for the PV10B? I only see the schematics for the Rev. A model, but perhaps I missed something. Thanks!

Hello
