They are not free, but the amplifier service manuals I have purchased through the site have been very good.

SOURCE: Audio Amplifier JVC Model A-GX3

If the service manual is not available on the JVC websites then you should just Google search "JVC A-GX3 service manual" There are many websites that archive manuals. You'll probably have to pay for a copy. Why can't you disassemble the unit and see the output transistor numbers first? More importantly how do you know this is the fault?

SOURCE: JVC AX-66 Integrated Amplifier seems to be muted?

You need to have a jumper between the 4 standalone jacks on the right side of the column of stereo connectors. A stereo RCA cable would work for this.

This model is the nearest one I can find, but most amps from the same manufacturer use common parts and circuits.

Technics SU-G75, No Speaker Output, Headphones Work. So I woke up this morning to find that my roof leaked ...onto my laptop and stereo. I love this amp, bought it new with all accessories in 1993,...


The fact you have output from the headphones is a good sign. It shows the main amp is working fine. However water has clearly got inside something and affected it. The best course of action is to trace back the wires from the headphone socket and see if there is a relay or anything that could get water in it. If you do find something, try applying warm air from a hairdryer. The alternative is to apply a soldering iron to the solder conections of the device. This should get rid of any water inside. If all else fails you might have to replace the relay. But I would try a spray of Servisol first. Just in case some dust has got inside or mineral salt from the water.

Stereo amplifier shutdown.


  • The amplifier is showing the protect mainly due to a safety feature on the power circuit. The fault could be failure or short in the output stages, short in the speakers, fault in the power ciicuit or the error amplifier that triggers the relay.
  • To trace the fault it is impotant to make the test in the main board, disconnect the power to output to confirm if the output is faulty. similarily disconnect the powering circuit one by one to identify. replace or disconnect to confirm. Hope this helps. Good day

I want to connect YST-Sw1500 sub woofer to the AX-596 amplifier .How can I do the connections .


on ur subwoofer u will see HPF output, connect this output to MAIN IN of ur power amp (first remove jumper between pre-out and main in from ur power amp) connect pre-out of ur power amp to input 2 L&R (Left is also for mono input). the HFP selector switch will cut off 80Hz or 100Hz to the main input depending on the position enabling u to have high frequency sound on your main speakers. connect the speakers to the main output terminal of ur power amp. do not connect speakers on the woofer ouput.
make sure u are using the right impedance speakers. do not switch speaker impedance selector while the unit is on.

How do i turn my protector light off of my amp?


I'm not really sure how your amp works but i can tell you that if that light is on there is probably something wrong. Check your ground wire. Also it could be your not getting enough power to your amp, or too much

Unbalanced LEDs> amplification problem, or mere graphic drop out?


This could be a defect in the metering circuit. In order to verify this, you should measure the output externally. Get that external measurement and post the results here. We'll continue from there.
