Unfortunately I can't find any more information on the net.
My unit differs a bit: - It is marked M and not M1. (On both units.) - The bag it came in is bigger although the same style as the one of Luis Paracampo in the photographs. - I got two units, both with a lightsensor cap on top but one has no photocell under it and the other one with photocell has no synch chord. - Noone of the units has in the metal part the engraving over the control lamp about voltgage, just an arrow pointing downward.
The last two differences are not very important, just mentioned them.
What would interest me: - What does the manual say about formatting the capacitor? This units were not in use for many years. (I know the usual manner to format capacitors, but I would like to know what the producer says.) - Which portable unit could be used with them? I have some batteries powered transcievers from other, not professional, russian flashes.
Ofcourse the scan of a manual would be very apreciated.
