Jobo Print Drums and extension drum

Two Jobo 2480 print drums with clips, lids light traps.. Perfect condition.

Jobo 2560 extension drum. This drum just extends the length and capacity of your existing 2500 series drum. If your current drum allows you fit one 2509 reel, this extension will extend it to be large enough to use 3x 2509's, processing 18 4x5 sheets at a time. or 10x 120 rolls at a time.

I only shoot 120 roll film and as such I only use 1500 series drums as they allow me to process more film in less chems. for 4x5 the 2500 series are the only option..

I also have a 2553 tank that I might sell with a cog lid. This tank is capable of holding 2x 2509n's or 4 2502 reels.. This is pretty much the standard for 4x5 rotary development.

Pretty much entertaining offers on this stuff.. its taking up room in my house and I'm not ever going to use them. That said I am not going to give them away.

FWIW, I'd be keeping the 25XX tanks and getting rid of the 15XX ones for 120.

Some information for Jobo's Newsletter (now long gone), circa 1999:

"So which tank system should you select? It all depends on your particular needs. If you will be processing mostly 35mm film, go with the 1500 series. If you are processing mostly 120/220, either system will work, with a very slight edge in favor of the 2500 series. If you plan to process roll film and sheet film and don't want to spend the extra money for an Expert drum, the 2500 system is the answer."

Also, a larger diameter reel (2500) means that there are fewer "layers" of film within the reel. This will mean a more even coverage over these layers. And, as the angle of attack of the film into the liquid is less on the 25xx reels as well as less layers, you'll get a more consistent and less aggressive immersion over more of the film for longer.

You'll also have the option of developing sheet film with the 25xx tanks. I develop 7x17" sheets in them.

Funnily enough despite all the theory I've had to give up on roll film in the 2500 tanks and go back to the 1500 series, I still use the 2500 series for 8x10 film and my 3013 for 4x5, but I found the reels for the 2500's covered more of the edge of the roll film than the smaller ones and I had problems with uneven developing along the edges which I never have with the small reels which overlap the film much less. The 2500 reels I've got actually cover part of the image area on 120 film so I used to get a lighter line along the long edge of all my images. Mine were the older transparent reels, the modern black ones may be better.

Hi Alex,

I've sent you a message about the 2553 drum, but I'm not sure it has sent fro some reason. Could you let me know if you've received it?

Oh - And with the recent acquisition of a 4x5 enlarger I have decided I will be keeping the print drums! :D
