[Cameramakers] Enlarger Transformers

Title: Message



I am 
working on building/restoring a large format enlarger and have run into a 
question on the transformer for the light.

Do I 
need anything special? Or will any transformer of the right voltage (with 
support for the watts) work?

regards 
Dave

To my understanding you ideally want a 
"constant voltage transformer".. I have several and they seem to 
bequite large for thier wattage output , but that would prevent any 
voltage spikes , or low voltage codition to help keep the light on a very 
level output..

How big is your enlarger?

For BW work, small fluctuations in color temperature and 
output are tolerable, so most supplies with adequate power 
will work. However, do not exceed the maximum voltage 
recommendation for the bulb(s), and actually measure the 
voltage when connected to the bulb(s) or a 100 W household
lamp as a load.

For color work, you will have fewer problems with a regulated
power supply which will avoid color shifts during peak demand.
