    So, I found this schematic, but I'm a little confused about a few of the capacitors on the schematic. What kind of capacitor should I use for C10? It looks like I need a 10uF non polarized capacitor, and they make those, but for testing purposes, I would have to use a bank of them in parallel to get that much capacitance. What about C24 or C4 or C26? would I have to use the came strategy, or could I put in an electrolytic with the negative side in as the shaded portion on the schematic?

    Thanks for any help. Reverb/reverbschem.jpg.html?sort=3&o=2

    Only C10 shows "NP" which is likely to mean non polarized. All other capacitors are standard electrolytic capacitors. At least for C15, 20 and 23 you can see the "-" mark on the capacitor's plastic envelope.

    The PCB shows a "+" sign even for C10, very irritating.

    Sorry, no great help. Maybe you get a better answer directly on the forum where this circuit was posted.
