Hello
I recently got a kenwood kr 7400 stereo reciever from a co worker recently. It had been in his shed for a while (2-3 years) and sold it to me cheap $15 bucks. I tool it home, looked through it and decided not to power it up since a lot of caps were visibly damaged, not to mention those two 2wattof resistors in the power supply that like to get toasty in this model and the 9400.
i did a partial re cap and put in replacement resistors at 10.5 watts. Tried to fire it up but nothing happened. I traced 120v ac on the four wire leads (red, white, blue, and yellow )are on the terminal post. The on/off switch only has around 4.0 v across it. There's nothing over the electrolytic can capacitors. I turned the reciever off and did a resistance check on both coil windings on the transformer. Winding 1 was 3.7 ohms between each lead, and a bitt around the same on the out put leads. There seems to be a complete path with voltage coming in, but absolutely nothing coming out?
HELP me please.
