That's too bad. I read someone (Jorge?) posted they had converted a Jobo Expert drum to work with a Beseler base. I thought perhaps the 1500s were the same size. I really like the 1500 tank I have (1510, 1520, 2x1530, 8 1501 reels) and don't feel like buying an entirely new setup, or a big honking processor like a CPA/CPP-2. I process my sheet film in an HP Combi-Plan but wouldn't mind something different like an Expert drum if I had a motor base. Mainly I just want to save on developer and tediousness. Oh well.
