Motiograph MA-7505 is a theater power amplifier series launched by Motiograph in 1941. It has a 6L6G push-pull design and 20 Watts output. The Motiograph MA-7505, which uses Western Electric's patented design, is itself the successor model of the Motiograph TA-7467A in the post-Western Electric era. At that time, the Motiograph MA-7505 was mainly used to promote the Western Electric Mirrophonic speaker system and was used as a power amplifier for sound movie theaters.

Tested in working condition with original cabinets. These are hard to find as a pair.
