Can anyone provide me the EI, Dilution and time for Tri-X 35mm? I want to use the Pyrocat HD minimal agitation or stand time. My enlarger is Diffuser head. I would appreciate any suggestion.

I am calibrated for condenser so you may want to increase the DR just a little - Tri-x320 at 320asa for 35 minutes at 70deg F in 1:1:150 with 4 aggitations total. Good to take and SBR of 7 and give a DR of 1.25

For 400TX in 35mm and a condenser enlarger I used:

Pryocat HD @ 1:1:100, 72 degrees, 7 3/4 minutes, 60 seconds initial agitation followed by 10 seconds of gentle inversion (2 full inversions) every 3 minutes.
