Hello from Italy

, I need help, I have a Truvox stereophonic model PD102 recorder, there is a cable disconnected inside, could anybody tell me where it should be connected? Thank you so much, Francesco

Hi Francesco,
I have a Truvox PD-102 and have attached a picture of the same switch. Hopes this helps

Thank you David, but I see too many differences, not good news for me, I do not fix recorders (I like only radios and TV's) maybe I'll try to show it to an old retired repairer

... Does anyone have an electrical schematic?

Hello Francesco,

Do not give up. The difference between the two machines is that your switch wafer is rotated 180 degrees from mine, but the wiring sequence should be the same.

In mine, looking left to right at the top half of the wafer, the sequence is PINK RED YELLOW. The bottom half of the wafer, again, left to right, BLACK BLUE GREEN .

There are two wafers on the switch and they are wired exactly the same

For your switch the wafer in rotated 180 degrees, so your sequence at the top left to right is, GREEN BLUE BLACK, and the bottom left to right is YELLOW RED PINK.

If both the upper and lower wafers are wired the same way the switch rotation does not matter, however if the one wafers is rotated 180 degrees from the other then you will need to make either the upper or the lower wafer the look the same.

On my machine one of the switch connections had broken off, so I was able to epoxy it back on again. This maybe the case for your machine
