I converted a federal to a point source, picked a 2 condenser model, up to 6X9, had a bulb that could raised and lowered and used a 120v transformer, rewired for a halogen clear bulb, worked really well, but so sharp, and the grain, the size of golf balls. Finally sold it to someone who said she really liked it. I still have a Stowaway Jr. 180 degrees from a point source, diffusion, built in 2 element lens which with the right negative works wonders. I need to set it up, I have a pile of 6X6 and 6X9 that I want to print soft.
