That would most likely be in the manual (and not the schematic). All conrad johnson manuals can be downloaded directly from their website.

Hi,

I am getting a MV52 serviced, and was looking to download a service manual/ schematics. I guess no one has one (its not among the zip files I downloaded).

Since we do have the MV50 and MV55 schematics, can the technician be able to use those, in place of the unavailable MV52 schematic? thanks!
