Would you be willing to send me a simple wiring diagram of the DPDT switch for this scenario? Where I would make the connections? Thanks in advance. I just thought it would be nice to stream some music from the same era as the console. You can rename each input so that the name can. That warm tube sound can usually be overcome by turning up the treble.ĭoesn't seem too complicated but I have to mull it over and decide if I really want to do this as I have numerous music sources to play from. You can connect devices other than those indicated above to the AUDIO IN jacks (SAT/CATV, VIDEO 1, and SA-CD/CD). A double pole, double throw switch could be added at either the main cabinet speakers or the remote speaker to accomplish this. If you switch the polarity on the remote speaker to play the I pod, you will have to switch the speaker polarity back when in tuner or mono phono modes. The tuner has a phase inverter tube that creates the second out of phase signal to drive the amplifier. One more complication, The AM-FM tuner signals are mono.
It will not work if the amplifier selector is in the "MONO TAPE" position because any common audio signal is cancelled out when they are combined and it sounds horrible. This can be corrected by reversing the speaker polarity at the remote speaker. The bottom line is that the standard in-phase audio signal from an I pod or a CD player will work in the "STEREO TAPE" position but the audio signals will be out of phase between the right and left speakers. The polarity on one of the output transformers is reversed to correct the phase and combine the signals. This allows the two single-ended 6V6 amplifiers to operate in push-pull mode when the selector switch is in any of the "MONO" positions. If you have ever connected a pair of speakers out of phase you know exactly what I'm talking about. The polarity of the left and right input signals are reversed. The inputs and tape output on this model are out of phase. That allows the RCA tape player to record directly from the phono or tuner sources. It becomes a line level output when the selector switch is in any other position. The tape jack is a line level input when the selector switch is in the "TAPE" position.
Another option is to pull the chassis and solder a pair of shielded cables directly to the lugs on the back side of the input jack and run the cables out through a hole in the chassis. The two RCA connectors plug into the back. One difficulty is finding the three pin plug and having the skill to build an adapter to convert it to a pair of female RCA jacks. To connect your iPhone, iPad or iPod to your home stereo you just need a 3.5mm to RCA cable like this cable above.
That 3-pin tape input jack should work just fine. Yes, it is absolutely possible but there are complications.
