Roll film had it's issues for me w/the 1500 series and I had a problem

surprised that the 2509 worked for you despite the warnings to not use
that drum/reel combo w/PMK. That warning is what drove me to get a
3010 drum and I never tried the 2509 w/PMK. Maybe mine was not the N
version?
Also I was using PMK before the used developer after-bath was declared
unnecessary.
So your friend's Jobo or pyrocat died mid-run?
Never a problem with PMK in the 2509N with either 4 or 6 sheets. As I
said, EDTA added to the PMK to control aerial oxidation (per Hutchings)
and Jobo speed set to P. The 3010 was designed for 4x5, no? I used a
friend's 3010 once and it was more of a pain than the 2509N. 5x7 or 8x10
in the 3005 is no sweat as Jobo says. I load wet with the narrow side
down and push to the bottom. EDTA again, and the speed of the Beseler is
perfect. My friend's Pyrocat died - he doesn't have a Jobo.
