I have a stereo system on my boat. The speakers keep cutting in and out. I have checked the wiring and all seems in good condition. When I first turn the system on the speakers play for a few seconds and then go off. Turning the system off and then back on getsthe speakers to work a few seconds then goes off again. OH I have no idea if I have a Kenwood CT 401 Hi-Fi stereo - I was thinking you guys would know the answer though. I really want to use the stereo on the boat and don't want to go out a purchase a new equalizer if you think it may be something else. - Thanks, Karla on the sailing vessel Serena

Re: do I need a new equalizer?
Karla, Equipment and water especially SALT water (AND SALT AIR) don't mix very well. The constant high moisture environment affects all the connections (the wires) the rca connectors (where one thing plugs into another, AND the switches. The wires may LOOK good but the connections may not be. When you say "all seems to be in good condition" tell me specifically how you checked them. Sometimes they LOOK good, but ar not making connection. While your stereo is ON, get in there and wiggle everything and see it the speakers come back on.
My first guess is your amplifier/reciever. Does it have speaker switches? If it does, move them up and down or click them many times to see if you can work the corrosion a little. This may help.
I'll try and help, let me know some of the stuff I've asked fo above.

The turntable goes into a Phono preamp in a amp or receiver then the amp or receiver will have the terminals for the speakers. The Turntable by itself can not drive speakers. It is a part of a stereo system.
The equalizer I have seen have Line in, line out, tape in, tape out and that is how you utilize a unit like this. The line IN goes to the receivers tape record out. The line out goes to the receivers Tape play in or monitor, The tape deck hooks to the equalizer. The record or input of the tape deck hooks to the EQ record out, the Tape decks output hooks to the EQ's Tape in connectors. All these are stereo so there are left and right sides which you need to keep consistent. Red on a cable means Right, the white or black on cables mean Left or the top RCA connector on most equipment. When playing back a tape the tape monitor is turned on with the receiver and left on. The way you record on tape from any source of the receiver is to select that source and it should go to the equalizer. Then the deck should record that source. To play a tape of the deck hooked to the equalizer then just press the tape monitor button on the EQ otherwise the Equalizer will just act as a loop and equalize any signal source that is coming from the receiver and the tape monitor on the receiver should stay on most of the time. Some equalizers have two tape inputs so you would hook another deck to that input and the owners manual of the equalizer should say how to select buttons to transfer tape signals from one to the other. If you master the concept of inputs and output of audio equipment then this hookup becomes another easy thing to do.
With audio problems if you look inside the unit, start the machine playing, then trace the wires from the tape head to the PC Board, then all you need do is touch the wires from the head with a small screwdriver. This should cause a buzz in either channel, if working right. Follow the circuit of the audio and keep probing. If you get Buzzing sounds near the output, and where the wires from the head enters, then there's something up with the head. But check for micro switches these can break and bend out of place so the sound is cut off.
If you get no buzz at where the head wires enter the PC Board, then there's a fault in the audio section.
As both channels are out you are looking at something common to both channels, for instance an IC.
always remember source, amp, then speakers. ex: cd to eq to amp to speakers and it goes: out from cd player into eq, out from eq into amp, out from amp into speakers . hope this makes it easier for you.
check your cables to the units channel that doesn't work, for breaks. Does the cassette player play back a pre-recorded tape okay? if it doesn't there might be a internal fault.
Check the wires to the tape head to see if one is off.
If you are recording from an outside source check the connections are good. If it does it from both IE dubbing and external it is possibly that a wire has detached from the head of the record head. The other likely source is the record amp inside the deck. Trace the leads from the Tape head (recording one) and see if you can locate a switch, these can get dirt on the contacts and cut out channels (clean with Servisol video 40). It could also be the electronics especially the amp chip!
If not then the head itself may have gone.
