| Hi,
I read your request. Did you find the schematics for the 3900z by the way? I have a receiver like that, with a blown ampli R-channel. Maybe you can provide me with clues where to look? Regards, Rene Hi Rene, Try to look for two fuses hidden inside a box. it's underneath the board for the main fuse... it's probably blown. Mine is always like that due to over volume |

| Thanx Zal,
I'm not sure about the rest of the site you directed me to. Lukily my Rumenian is not so good to read all the links, but I guess some terms are International,... To whom it may concern, I have cured the problem in the right channel. Seems that resistor R28 crashed & burned. I will replace it and enjoy the music from a receiver I bought for 8,- euros. Regards, R. Marell |

| Hi Boggs,
Thanks for the tip. Would you also happen to have any clues for me to repair a R-channel. I've transplanted most transistors from left to right hoping that I would move the problem to the left channel. Left channel still fine, right channel still no sound... Regards, rene69 |
