    Marantz 4300 won’t come out of protection after amp rebuild

    I have a Marantz 4300. I used it for a while before I started getting a crackle in the left channel that wouldn’t go away no matter what I did. I then switched the amp boards around.

    Marantz 4300 R744 smoking

    Hey guys, so I have a Marantz 4300 I'm currently working on, I swapped the 2SC458s in the amp board to KSC1845s and everything seemed good so I went on to recap the board and get rid of the VD1212s. I went wring somewhere apparently as R744 seems to be going up in smoke. Any ideas why? Pics...

    I have a Marantz 4300 that I can not for the life of me find out why the right rear channel is weak. I rebuilt the power supply and the voltage is at 35v.
