    I intend to document every stage and every issue that arises. I will be recapping and dealing with meter lights at first and go from there. I would also like to do some resurfacing on the wood to make it as shiny as I can.

    Fix issues first before you start swapping out parts.

    To me this seems like quite a challenge. The beasts I have let me know when they need feeding. Best of luck to you

    so it works but upon more listening not perfectly. likely due to the short in the right channel speaker terminals that lasted few seconds or maybe it was a previous condition but now i see that after several minutes of playing, it makes crackling sounds and one or both channels go out and come back.

    Have a real close look at the power supply. Post a clear photo of the two large heatsinked transistors on the power supply board. Its located in the belly of the beast.

    finally opened it up, while dirty, seems to be untouched. it actually seems to be slightly easier than A-1 to take apart. in the sense that there is a little more space in there to stick your hand in. imma start with the power supply.
    the problems are there also when using the pre pout to another amp so like avionic said, the power supply is the first thing to inspect.

    this is just so clean. i dont see anything even slightly off. just that the board is darkened (scorched) under those two trans D476A and B566A. what is to be done about it?

    Mount the transistor and heatsink a little farther off the board. Or figure out how to get better ventalation in there.Larger heatsink ?
