Would anyone know where I might find a schematic and or other service documentation for a Seco 107C? The tube chart does not include a schematic just like my Seco 107B does.

Thanks

Hi! I too cannot find the document, cards for Seco 107c. At me a copy from the Internet and they do not coincide, these copies for Seco 107 and 107a. When you have the information inform me please. Yura
