English grand Lumley's stereo power amplifier started under the close relation with The M-O Valve Company famous as a vacuum tube maker.

A circuit system is as common as GL-50A, and the output is heightened by using KT-88 for an output pipe at GL-100A.

It is not based on a printed circuit board, but the GL-50A said appearance is made in the hand wire ring using a lug board.
