  • The finest amplifier kit we have ever offered-- check the features. This inexpensive amplifier compares favorably with instruments costing five times as much. Nothing has been spared to provide the best reproduction.

    Power transformer is conservatively rated for continous operation in sound systems. Tone control gives maximum bass boost of 6 db at 70 cycles. Amplifier has maximum gain of 75 db. Response within ± 3 db 20 to 20,000 cycles.
