Mod 2245 marantz no sound right or left.


Hello,

Do you hear the relay click when you turn the unit on? If not you have a issue with one or both amps. If you do get a relay click, check your pre-amp out/main amp in connections on the back. You may want to also play with your controls, dirty controls can cause this condition as well. If you would like to have the unit serviced, check out my website, I have a lot of experience with the vintage Marantz units.

Thanks

Have a Harmon/Kardon AVR 20. The right channel produces an extremely weak signal when playing music through any input. (Yet, once I hit the "test" button, the sound hits each speaker equally). Help!


It sound like it could be the pre-amp that is playing up. The picture you posted shows that the pre-amp can be listened to separately. All you need to do is pull the two black jumpers out. And connect a separate power amp to the "pre out" sockets. Leaving the other two not connected. If the weakness is present you will know it's in the pre-amp and not the power amp stage of your amp.

Can i play records through my sherwood rd6108 receiver? When i try to play a record i get no sound no matter which channel i use.


Record players require a PHONO input on an amp.
Most amps no longer have this, so you will need to source out a pre-amp for the record player, and then you can plug the record player into the pre-amp and then hook the pre-amp into a tape, DVD or AUX input.

FM tuner does not play


Hard to say without knowing more, but many tuners have a squelch function that "mutes" the output unless the signal level reaches a certain threshold. You might want to look at the control panel and search for such a switch and de-activate it.
You didnt say if this was connected to an external pre-amp or a power amp. If so, the issue could be simply one of the correct cabling and selector switch setting

Hooking up Turntable to Yahama HTR-5660


you have to have a pre amp, or an old reciever with a phono input.

you dont have to use the aux input, the cd or md-cdr inputs will be fine, but you do need that preamp for that reciever
