Commentary
This is a stereo power amplifier from Grand Ramray Inc. in England, which started under the close relationship with The M-O Valve Company which is famous as a vacuum tube manufacturer.
The circuit system is the same as GL-50A, and GL-100A uses KT-88 for the output tube to increase the output.
Like the GL-50A, it is finished by hand wiring using a lug plate instead of a printed circuit board.
