Knowing (or believing to know) the exact problem with the power supply, I continued with assembly of the enlarger.

I have started to work on the cold light. I opened it up and it has the W45 lamp that I can use for multicontrast printing (Yeh!). The number is printed right on the glass tube.

I just set the coldlight on top of the enlarger and did a dry run to get a feel for how high the column needs to be to make a 11x14 or a 16x20. This picture shows the position of the head, table and lens stage for a focused 16x20 print (300mm lens, 8x10 negative).
