You must have not caught the later post where I changed my mind and decided that Ray's suggestion was better. What I wound up doing was connect a 47k fixed resistor (to ground) in series with a 50k 10-turn trimmer and used these to replace R49 (if this is the resistor across the bias supply to ground - don't have my schematic handy). Works well and gives me a range of 45-85v if I remember correctly.
