Motorola value! Thats a fairly simple amplifier; with each 6BM8 pentode driving mid-high speakers at 5-watts, and
each 6BM8 triode serving as the preamp for the ceramic cartridge.
The 6BQ5's grid then has to be driven with both channels to push about 10 watts to the woofer. I wonder how that is done, summing the L+R channels to feed the 6BQ5 without compromising the stereo separation...
