My request for help involves the amplifier for the Seeburg Coon Hunt rifle game. Specifically, the amplifier can not be adjusted within the ranges of settings provided by the manufacturer for the gun lamp to properly illuminate the photocells, produce adequate electrical impulses, become amplified, fire the 2050 tubes and energize the score relay coil. Any help with voltage measurements, procedures, and other advice would be appreciated. The game is 95% restored to nearly new condition. Thanks. Ron.
