I recently acquired a dusty old D2, which I cleaned up and have just got around to testing it out. I'm getting really spotty prints, with lines in them that matched up to the larger condenser lenses, i switched them around and got some better results putting the nicer lens closer to the negative and the bad one further away. I think the person who gave it to me had it sitting in their garage through many cold winters and hot summers, causing the glass to damage. Holding the condenser lenses up to the light there are many specks and tiny air bubbles in the glass.
I'm wondering if replacing my 75w bulb with a brighter 125w if it will help cut through some of the imperfections in the condenser lenses, or if I should invest in some new lenses all together?
