In the web site of Meopta, search the "Historical Products", within the section "Download". Unfortunately, the instruction manual of the enlarger Magnifax 3a is available only in czech language. However, the instruction manual of the Magnifax 4 is available in english language.
The darkroom products are classified as "historical" because the Meopta has unfortunately taken out of production the entire range.
I just received a used Magnifax 4 with the colour head 3 and the b&w condenser, but no manuals! Do you have an idea where I can find one? The Meopta museum has none, and the eZine shop is too expensive! I was hoping for a PDF or a nice instruction site!
