I just wanted to let anybody interested that contrary to the manual and the info rmation on the Jobo site, the 3004 drum (allowing developing of 4 sheets/paper u p to 8x12") actually fits in the Jobo CPE2. I just got the drum and I was prepar ed to modify the bath to make it large enough but it doesn't need to be. It fits perfectly (barely of course). And for whiever is concerned about the motor not being strong enough, the JOBO CPE2+ has the same motor that the CPP has (the one that was "designed" for the 3000 series drums). So, basically, what I'm saying is that the proffesional drums are actually working with the CPE2.
