Conrad Johnson PV-1
Conrad Johnson PV-1
I recently acquired a Conrad Johnson PV-1. I am not very knowledgeable about the circuitry in this preamp. All I know is it has had some upgrading done to it. For good or for bad I don't know. I am inserting a pictures of my preamp including the inside and if anyone would like to comment on this I would appreciate it.

Re: Conrad Johnson PV-1
Welcome to CJO. Great to have you with us.
I think this has been modified. I don't recognize that vertical board in front of the transformer. I don't think that is original. You would probably have to grab the schematics and try to figure out what has been changed if you do not have the modification history for this unit.
