I have a customers' amp, that checks out in every respect to voltage, power and gain specs shown on the schematic, but has to be run at "10" to be loud. Won't really distort, will go to about 92 of rated 135 watts. The tests showed every measurement to be within 20%, at the low side, but still won't overdrive, even with Master volume down and gain all the way up? One tech I know says this is normal with current tube quality, owner says bull- he just bought the amp off the Net. Help!
