    I just got my hands on a Jobo CPE2 but don't have a users manual or any other information on it. I need to get tanks for it and need to know which ones I should look for and what won't fit. Can anybody help?

    I've been running a Jobo CPE2 with lift, since the eighties. If you can tell me what you wish to develop then I can probably tell you the most efficient way, drum wise, to go about it.

    You can do 35mm film various ways, but the 1500 series of drums are the cheapest.

    1510 drum holds one 35mm roll and uses 140ml (150 to be safe)

    Adding a 1530 extender, which comes with a film reel core that will twist onto the 1510 core. Makes the drum into a two piece 1540 drum. Holds 4 35mm or 4 120 rolls and uses 470ml (500 to be safe).

    1520 drum holds 2 35mm or 2 120 rolls and uses 240ml (250 to be safe).

    Adding the 1530 extender to the 1520 makes it a 5 roll 35mm or 4 120 roll unit. 600 ml solution this is the maximum that the CPE2 can realistically handle, especially the earlier units, which is what mine is.

    If you take the 1520 drum add the 1530 extender, then you have a rotary drum that holds 1 8x10" paper. It is identical to the 8x10" drum with the exception that it doesn't have the paper solution sticker on the outside of the 1530 extender.

    The largest piece of paper that you can put through the CPE2 is 12x16". For this you need the 2840 drum, which is a two piece drum. This drum with it's little click in plastic bits allows you to hold 2x 8x10" paper or 4 x 5x7" paper (I think). Whatever, but this drum has another interesting thing it can do, it can also process 4x5" film"

    By using the small base piece of the 2840 drum, which officially is called the test print drum, you can develop up to 6 sheets of 4x5" film. You will of course have to buy the correct film reel, and should also buy the film loader for this reel.

    I personally use this small drum for 4x5" film but only load 4 sheets at a time. Once you see the closeness of the film sheets, you may decide to do only 4 instead of six as I do.

    In a nutshell this is about the cheapest and most efficient way to develop film and paper that I know.

    You may have heard of an optional E6 kit. Well the E6 kit is a different red coloured, bottle holder that takes 6 500ml bottles of solution instead of 4 500ml bottles and 4 x 250ml open measures.

    The E6 kit consists of the red bottle holder and two more 500ml plastic bottles.

    Mick.

    I've seen that theres some jobo setups using metal reels that slide onto a plastic core tube. What uses these and can the usual stainless reels be adapted to work?

    Gary I have made a 100+ page pdf manual for the jobo. If you want it drop me an email. It's 1.5mb

    All the help has been wonderful! I got my first tank, a Multitank 5 (2551) with two 4x5 reels. I plan on doing chromes. Will 600ml do a full load of 12 sheets? I have a Unicolor kit and Provia, any recommends on proper times for this?
