My Jobo 1510 has slots in the core part that let air escape as you pour liquids in. As I discovered last night, my 1520's core lacks these, and consquently pouring the chemicals in is a real pain, as you have to wait for large bubbles to make there way up through the core, rather than having air escape steadily from the top. I can fill the 1510 in 5 or 10 seconds whilst the 1520 takes around 30 or more, which a)bores me and b)messes with my timing.
Are all 1520s like this? I bought mine used so I've no idea how old it is, but the problem is annoying enough that I'd like to buy a new, improved core if such a thing is available. Alternatively I could take a knife and/or drill to it but there's a fair chance of that going wrong and creating a light leak.
By the way, here's a frame from the roll I was doing last night - my first time developing 120. This is my mother on HP5, in ID-11. The camera is an MPP Microcord, wide open at f/3.5.
Thanks,
Matthew
