Sony STR-7065 Just burned me

Vintage Solid State - AudioKarma.org Home Audio Stereo Discussion Forums - www.audiokarma.org
Hi.

I did something dumb and got a second degree burn on my finger. It hurts like a crazy right now. Here's what I did.... I just got a Sony STR-7065 off the bay. (dang it sounds fine) Put my meter on the speaker terminals and left channel is 135mv, right is 15mv. Then I noticed that the heat sink for the left channel was pretty warm while the right channel was slightly above room temp. THEN I saw a dingy looking grey resistor(I think) and touched it with my finger for some unknown reason. Immediate burn, immediate blister, hurts like a b**ch, can only type with one hand right now.

The pcb board around this resistor is slightly browned, big surprise. So a few questions.

1. Why is that resistor so hot? Seems like a fire hazard.

2. Should I do a re-cap of the vertical board on the left side and will that fix my issues? Or do I need to re-cap the whole shebang?

Pics attached for fun. You can't see the b*stard that burned me, but it is on a board on the left side, near the speaker outputs, near some light-blue caps...
