if two regulators are in parallel do I need two .33 micro farad capacitors, one on each input side of the regulators or will one work for both regulators? And what type of cap would work best for audio device? And can I use the base-emitter junction of a transistor as a .7 volt zener diode?

Best to put caps as close to the input and output sides, so each regulator needs its own caps. As for the zener best to use an ordinary silicon diode.

thanks for the input guys my DC offset went to zero with the diode once I put the diode on the other side of the coupling capacitor.
