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.

200 watts is the output, home use or commercial? not a good amp to run at its max as it has a low reserve headroom. for home use 100 watts rms is more than enough.
