Is it the resistors near the relay? that would be 10 ohms. You may replace it with a higher wattage (like say 5 watts)

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: how can i upgrade my av 302 to becomes best as

Hi,
upgrade your 302 to 502 need to replaced the toroid transformer, set of output amplifier, set of electrolytic capacitor.
Purchasing of these parts one-by-one is much expensive rather that you buy a brad new Konzert AV-502. Also upgrading the unit is quite tech and need a lot of experienced in electronics.
Hope that it may help you.
Have a nice day.

My amplifier is konzert 502a no sound of speaker a and b but sorround is sound it is capasitor


It is most likely NOT a capacitor. Not all problems are from bad capacitors. You may have DC Offset(a damaged amplifier). (It's hard fro me to understand your English). If you need more assistance, or would like to inquire about repairing your unit, please visit my website at audioserviceclinic.com. You may contact me there. Thank you.

Konzert model AV 502A


Disconnect the speakers, all of them. If the fuse continues blowing off, you have a short circuit in the final stage of the device, called the amplification circuit. If the does not blow , then the short circuit in is one or more speakers.
