How to Tell the Polarity of an Electrolytic Capacitor
To figure out capacitor polarity the stripe on an electrolytic capacitor tells you the negative end. For axial leaded capacitors (in which the leads come out of the opposite ends of the capacitor), there may be an arrow that points to the negative end, symbolizing the flow of charge.
Choosing Cathode Bypass Capacitor
You can look for JJ''s 550 uF/ 385V electrolytic cap too. Axial electrolytic caps might be a slight improvement otherwise I really can''t hear any difference between "audio grade" and normal good quality electrolytic. If you want better caps you have to forget electrolytic capacitors and in your situation it becomes expensive and bulky, I …

Electrolytic capacitor: Properties and operation
Electrolytic capacitors consist of two electrodes (anode and cathode), a film oxide layer acting as a dielectric and an electrolyte. The electrolyte brings the negative potential of the cathode closer to the dielectric via ionic transport in the electrolyte [7] (see Fig. 2).The electrolyte is either a liquid or a polymer containing a high concentration of …

Why can I put an electrolytic capacitor on AC?
One way in which electrolytic capacitors can be used in an AC circuit is to put two in series polarity-opposed. Each capacitor will tend to "deal with" the appropriate part of the waveform. The reverse biased capacitor will pass much current at low reverse voltage and use the other half to block forward voltage DC.
Explaining Capacitors and the Different Types
Aluminum electrolytic capacitors marketed for audio applications are commonly low-ESR types, and design compromises in their construction may be skewed in favor of electrical performance and parameter stability at the expense of things such as size and cost. It should be noted however, that the audio field is riddled with subjectivism and ...
