Michael,
D-76 specifically seems immune to the streaking problems most other
developers cause with print drums. Jobo sells the large print drums with an
insert that modifies them into "Expert" film drums, but the price is high
and you can do only one sheet per run. It does allow use of a full range of
developers. Whether you could do a home made version of this I don't know,
but suspect it is possible. D-76 for Jobo print drums is an excellent way to
go, but for most work it means targeting the negative development
specifically for either silver or Pt/Pd. Pyro has the advantage of printing
very well either way from the same negative.---Carl

> Hello group,

> I have searched the archives and noticed that about two years ago, there

> Carl had mentioned that he does his 7x17's in trays because he was
> unable to get even development in the JOBO, and Kerik is using home made
> BTZS style tubes for his 7x17 with success. I'm processing for platinum

> I have a Jobo and been having no problem with uneven development with
> Tri-X in D-76 in the print tubes for my 7x17 negatives. Now I want to
> try pyro, so I thought I would revisit the question one more time:
