i got rid of the small specs and lines by switching around the glass in the main diffuser, except for one somewhat prominent spec that turns up in all prints. it seems to be fine for 35mm, but the specs become quite visible again using a 135mm lens for medium format. no go on the brighter bulb then... im really considering a cold light head, but the time and cost of finding replacement bulbs for them seems like a nightmare... not to mention the issue with printing on multigrade, the whole thing sounds like a hassle. the main condensers are 6.5 inches, the variable condenser is 4.5, but is far enough away from the lens it doesnt SEEM to be causing problems. the condensers are full of many, many, many small spotty bubbles within the glass. im in north jersey.
Bill, what stage of the DII did you insert the opalite? Also, mine is a variable condenser...
