Uniden Washington (1998 vintage) Driver bias current way too high

I recently purchased a Uniden Washington base station at a ham swap meet that looked to be in original condition. I got the unit home and discovered several problems. First, the AC power transformer had a burnt winding in the primary which I have been able to fix. Second, there was no measurable rf output. Turns out the driver transistor (2sc2166) was blown. Completely open, no continuity between any of the leads or tab. Also, C206 appeared to have arced as it had black soot on one side. The radio receives well and the unit is on frequency. Doesn't look like any of the usual mods and the overall condition is really clean. I initially suspected a power sure or near lightning event to have caused the problems.
I have replaced the driver transistor with a new original 2166 from a reputable source. The radio now keys up with full power and modulation. Problem being is the driver and final bias currents are way too high. the driver has 275 mA current on AM with no key up and is about 950 ma when keyed. also, the driver bias current jumps up to 450 mA in ssb modes and over 1.5 amps when modulated. needless to say the PA section gets real hot real quick.
I am using an external 13.8 VDC power supply when testing. The bias voltage is running about 8.3 Volts measured at the pins on the board where the green and violet wires connect. I sure would like to get this old radio up and going.
