I have this nice Simma Sine Wave Roller, wich I pimairly use with a Jobo 3010.
I do have a nice set of print drums now (upto 20*24 inch 50*60 cm), which enables printing bigger than 30*40 (my darkroom is rather small).
I did test drive 30*40cm FB in a Simma drum, which worked out fine, apart from the fact that my developer oxidized rapidly judged by the fast colour change to brown. I assume that the developer is sloshed around too violently and thus get oxidized.
So I would like to slow down the speed of the roller with a dimmer. I got this Thyristor dimmer, can I use that without out harming the electro motor of the roller? I am not to well versed in electronics, and would hate to destroy that nice roller (I run 220V, but I guess that that is not important).
Thanks in advance,
Best,
Cor
