SOURCE: components do not work

Yes there is bound to be at least one internal low-voltage fuse - so get inside with unit completely removed from any mains source!!
Good luck.

Hi,
Check for the speaker separately for proper working? If needed change the speaker and check it ok.

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.

How can i upgrade my av 302 to becomes best as konzert av-502


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.
