I am wanting to get some information such as a schematics on my Operadio Photocell Amplifier that is housed in my 1946 Amusing Telequiz Educational Arcade Game. So I would assume the age of the amp is also around 1946. Like I had mentioned it is a Operadio Photocell Amplifier Model X-230 Serial # 194. It has a Tube line up of 6X5GT tube along with 6V6GT tube, 6SL7GT tube and a 6J7GT tube. It also has 6 photo cells houser in it also with a gain control. The amplifier is fused wit a 1 ampere fused to the extreme right. What can anyone tell me about this amplifier and would anyone possibly be able to find me a schematics to this Amplifier. Any information would be greatly appreciated.
