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!

Just download the zip file and open it, it's too far down to be listed in the "preview" I think. It is in the PV5 subdirectory.

(I removed your posted link as that is for members only).
