Thank you for the suggestions.  I posted on that forum and hopefully will have some luck there.  I'm looking at the signal tracers online as we speak, and will look a bit more during my lunch break.  Thank you again for the information.

Thanks for the suggestion.  I finally found the model number inside the compartment that held the amp.  It looks like it is a Model number x560-2.  It lists wattage as 50 watts.  I am still working on pictures and will see if I can come up with anything but the schematic would be incredibly helpful.

Thanks!

Good evening everyone. I'm dead a newbie but have some small amount of experience with simple audio circuits. I found this zenith solidstate record player in my wife's grandfathers garage. It's an all in one unit with speakers that hinged out. The phono was not functional so I dug in and started to try to see if the amp was functional and discovered that at least one side of it was. I was able to tap into the circuit and plug my guitar in. Since then I have been reading about RIAA curves and I'm wondering if this has it and if I'll be able to bypass it. So my questions are as follows...

1. Where should I start on the channel that doesn't seem to be working.
2. To bypass the RIAA should I just trace the circuit back to the power amp and then attempt to use a probe to see if audio comes out? Is there a way to protect my sound source in case accidentally probe some place carrying power?


I sincerely appreciate the help. I hope that I am not real far off base. I will try to snap some pics of the circuit for reference some time tomorrow if that is helpful!

Thanks again
