I have the same result from my VK-200. The right channel works perfectly, but the left channel has no audio output.
Anyone know what else a bridge rectifier going out can cause problems with? That is, what in the output section or powering the output section can be destroyed by a bridge rectifier going out (burning up)?
My first thought was an output transistor, but they are located on the bottom of the board whereas the bridge rectifiers are onthe top of the board. It seems like there would be manythings in between to be destroyd before the output transistors. They all "look fine" but I realise that doesn't mean they work.
Can you guys give me some help in there I should start testing for other bad parts?
Please let me know if you need more info.
Thanks for the help......
