OK I'm usually a hybrid guy, but when my friend liquidated his darkroom a couple of years ago, I bought his enlarger, and it's been in the basement ever since. I've decided it's time to have a go. I have lots of questions. 1) The bulb is dead. I can go to my local hardware store, and I'm pretty sure I can get another bulb, but it won't be specifically an enlarger bulb. The bulb which came out says 100W 12V Durst, made by OSRAM, and the serial number is unreadable Will I be OK with a generic domestic 12V 100W halogen? Am I right in thinking that if it's a diffuser enlarger, then the bulb won't matter too much as it will be diffused anyway? I am shooting only BW, so I guess colour balance doesn't matter too much. 2) I'm wanting to print mainly 6x6 and a little 6x7. The lens I have is a 75mm f4 EL-Nikkor. Is that going to be good enough? I'll be printing on 8x10 initially (although at some point I guess I'll want to investigate square paper, if there is such a thing...) 3) The enlarger is an M707 COLOR and it comes with a funky regulated power supply and timer thingy. I shoot black and white only. Is this head a condenser or a diffuser, and is that appropriate for BW work? Thanks, and sorry for all the questions.
