Yamaha C-60 Woofer Pumping Problem

Are you grounding your neg test lead to "E" copper bus. And probing with the pos test lead to each end of the two resistors Should have +/- 27-28 volts on either end of each resistor.
 
Now select AC voltage on your meter and measure the AC voltage on the two red wires coming from the transformer each wire should be 23vac.
 
Go back to DC voltage. I need to know the base and emitter voltages of TR149 and TR150.
