Bill he lists a PC602 board, wouldn't that mean he should also have or need a PC502 board and the "missing" power transistor? Schematic I have shows the 602 as the minus supply and 502 as the positive supply. Just to double check went down to my bench. My A without effects just has a PC502 board in it with space (holes) in the chassis for an additional board. It is the positive regulator. The other unit with effects has both the boards a PC502 positive regulator and a PC602 negative regulator. While this should have nothing to do with his voltage on the speaker jack it will affect the units ability to function if he truly only has a 602 board along with the driver / output board on the back wall. Unless someone cobbled a +24volt supply out of zeners.
