Narrative:

Just a short note about a mechanical issue. We had a los of both automatic and standby pressurization controllers early in the climb. We were able to pressurize and continue using the manual system. One thing I want to point out is that we were dispatched no alternate as the WX was good; but I put on an extra 1000 pounds. I'm glad we put on the extra fuel as we burned more than normal dealing with the pressurization issue. Ultimately landed with 4000 pounds.
