Old school Autotek repair question w/pic

[beco]

I just bought this amp off of ebay and noticed 2 burnt resistors on the board, the rest looks good. I was wondering if I could replace them myself and get it to work? I have several pics but they are all to large to download. If anyone is interested in helping me I will be than happy to send you a pic. I really want to get this thing running. Thanks

Send them to me and I'll see if I can help.

Those won't stop the amp from working.

Is the amplifier inoperative?

What are they for then?? I haven't tested it yet.

The resistors are part of a Zobel network. They are across the output terminals of the amplifier (parallel to the speaker). They help stabilize the amplifier (reduces its tendency to oscillate at high frequencies) when the load is extremely reactive.

They need to be replaced but the amp should power up and produce audio without them. They seem to burn most often when the amplifier is abused (driven into severe clipping for long periods of time) when run full range or high pass.
