Roll film had it's issues for me w/the 1500 series and I had a problem w/5x7 in the 3010 drum w/unevenness and lack of proper fixing. I'm 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? ________________________________ From: Chauncey Walden <clwaldeniii@xxxxxxxxxxx> To: pure-silver@xxxxxxxxxxxxx Sent: Thu, May 19, 2011 1:53:10 PM Subject: [pure-silver] Re: ADV: Re: Efke R100 Chapter 2: PMK I have had no problems with rotary processing sheet film in PMK with EDTA. 4x5s in a 2509N on the Jobo and everything larger in a 3005 on a Beseler base. If you try it in a ribbed drum or on the old Jobo dimpled holders it is a different story. As far as Pyrocat is concerned, a very experienced friend has produced some beautiful clear negs when it died unexpectedly mid run. Chauncey
