I have an LPL6700 which was given to my father by a Canadian who moved to the UK and brought it with him. I run it from a transformer as it is designed to run from 110-120 volts. I believe it uses an 82 volt, 85 watt bulb and the power is derived via a diode in series with the supply (half wave rectified 115 volts being 81 volts RMS). There is no factory supplied transformer with this enlarger. The mains lead goes straight to the head. Does the UK version of this enlarger come with a transformer or is a different bulb used? I am setting mine up in my new darkroom. If there is a different bulb which will run from 220 volts then I may get this and dispense with my step down transformer. If not, I will have to carry on using it as it is. Steve.
