Don, The only reason that I could afford the Jobo CPE processor is that I managed to pick it up cheap at an auction. although it's primary use was for colour, I also used it for developing my B&W film and for B&W prints as well.
I sold all my film based equipment shortly after buying my second digital camera (Minolta D7) back end of 2001
I remember only to well using a washing up bowl filled with hot water, The temp for B&W wasn't too critical, but processing reversal was, so that was carried out over the kitchen sink.
Safety didn't seem to be a concern those days, for the second exposure of the reversal film I used a 100w 240v photoflood suspended approx 18 inches above the water. Residual Circuit breakers had not been thought of then
What a merry time we used to have, the best thing that ever happened in the photographic world was when it went digital.
