How would i play my ipod (low level input device) into the amp that is in a old record player. i got the amp to turn on removed the record player part, the tubes glow and the speaker has a faint hum. it has a 12AX7 preamp and two 50C5 at the output stage it even has the circuit diagram. the amp in in a little metal box and it has a 120vac power cord on it and two wires where the record players stylus connects could i connect the two wire in series with a 2meg resistor to lower the volume of the ipods audio signal so it would amplify the ipods audio signal.
