Hi, first post, jumping right in with a question, hope that's okay!
On another forum, I have been trying to plan out a chip amp build with an STK 463 stereo amp chip, which would be pretty similar to a gainclone. Here is the current question. In the suggested power supply from the datasheet (see below), there are two 500ohm bleeder resistors. Wondering if anyone could help me understand why 500ohms was chosen, and how I should adjust if using an additional pair of 4700uf caps?

For this low freq PSU application biggest capasitor is the best. I think bleeder resistor just for discharge the capasitor after it turned off or just for idle load.
Okay, but doesn't 500 Ohm seem on the verge of being too small? Seems like these are usually more like 1.5kOhm-5.5kOhm.
