The electrolytic capacitor that has the positive lead going to ground is connected to the center tap of the power transformer that feeds the plates of the rectifier. I can not read the number of the capacitor because it is blurry on the download from Nostalgiaair.com. This is correct for this capacitor's positive lead to go to ground.

The connection generates a negative bias voltage for the control grids of the audio output tubes.

Number 31 looks like it negative lead goes to ground.

Best Wishes
