Re: marantz 7t

You could try to find the problem with a multimeter.... but i suggest perhaps some experience on vintage amps would be required also. ;) This old girl is a sought after collectable classic these days. I would first check that all connections to and from the preamp are ok by interchanging leads. If this does not point to the problem, is it independant of the vol control or not. I will need to ask a few more questions to help you from here

How do I check the internal wiring for input voltage on a Marantz 4060 Quad Amp?

The only way would be a voltage selection switch on the back of the unit, or changing pigtail leads on the primary side of the power transformer.

Looking for a owners manual for a marantz pm432a to reveal what the power out put per channel

Try the Marantz website they might have a free PDF of the manual. But I'm certain an E-Mail to them would give the answer you require.

Hi can I hook up my marantz mm500u amp to my pioneer 305 vsx audio reciever

I presume you just want to slave the Marantz to play whatever the Pioneer is playing.

Run a pair of RCA cables from either the Pioneer Tape Monitor REC or the VCR/Tape 1 Out jacks to the desired Marantz Input jacks. DON'T activate the corresponding switch on the Pioneer.

Only the basic Leftand Right channel programming that the Pioneer plays will be available at the Marantz. You will NOT have centralized volume control at the Pioneer.

Where is the internal fuse of marantz pm7200
The top link is for a manual for your model. The second link is a Fixya link concerning "no power". I'm not sure why you are looking for fuse but, have to assume it's a no power issue.
The above link is a support link for Marantz. Hope this helps.

Marantz dedicated amplifier squeals

The symptom sounds like a feeback loop. As long as that indicator is showing near maximum output on one channel AVOID ATTACHING ANY SPEAKERS TO IT!!!! You'll cook the tweeters.

Turn it off and manually operate every control, knob and pushbutton throughout its range many times to wipe oxides away from their conductors.

Set all EQ controls to their midpoints and re-evaluate.

We don't know if it's an input or output problem yet. Does it do that with all inputs?

Marantz pm 7200 lost sound, only works when volume is up high, still looks like there are no high or medium frequencies.

You have either lost the pre-amp stage or the Main Amp stage. Since you have a problem on both channels it most be a part that is common to both channels. Something like an IC I would suspect.

Marantz Pm-7200 left channel weak compared to the right

hmmm. Let's start by swapping the wires you are using for your speakers. Double check the wire connections first, then take the left and place iton the right and vice versa.
