I don't post too often to the list but here is my 2 cents.
I use the JOBO 8x10 tank, the 3000 series, often to process 8x10 B/W
negs using Pyro for Pt. printing with no problems what so ever. That
same drum is used for 8x10 E-6 achieving beautiful results. The back
of the film must receive solutions in order to wash off the
antihaliation backing.
And yes - pyro does increase my Pt printing times by about 50% but
the wait is worth it.
Thanks for allowing me to share this info.
