Service Manual Pioneer C73

[Macrom]

Hello

Is there anybody who could provide me a service manual for the pioneer C73 pre-amplifier.

I have a problem with mine.

Please use: student_fhc@web.de

Thank you very much

Kind regards
Stefan

What's the problem???

Hi Leolabs

There is no output signal on the PreOut jacks.

When ich apply an input on any source inputs I can pursue the signal till the uPD6362 IC.
After that I can´t find it anymore.
It would be easier to search for if I had a schematic.

The voltages on the board are ok.

regards
Stefan

If it is anything similar to the C-90, there are a lot of relays that often fail with age...
You may also check the switching function in the phone-plug (some pre-amps mutes the main-output when plugging in).

C73 no output

Hi,

although it's a long time ago, did you succeed in repairing your Pioneer C73 ? And if yes, what was the problem ? I am currently in the same situation.

Thanks !
