AMPRO PREMIER 20 16mm
The Premier 20 is a derivative of the 1936 models J&K and also of The American Ampro-Arc. It gained its 20 identity because of its powerful 20watt amplifier. With a 1000watt lamp it was capable of large auditorium work. The amplifier gives a clear reproduction of sound through 70 to 7000 cycles via a single extension speaker. Manufactured by simplex Ampro, Great Britain.
