While I agree with Sean that multiple filter caps result in a lower ESR. I do not share his affinity for Schottky bridge rectifiers. They will work but the expense/benefit ratio is very low. The jury is out on the benefits of Shottky diodes. Some say the diodes need to be fast to respond the charging requirements of the electrolytics but lets face it, with modern amps having 50,000uF + of capacity per rail, the discharge time constants are so long that regular diodes have no trouble keeping those caps charged.
Upgrading Power Supply Caps
I'm about to purchase a fine used amp. Over time, however, I can see going the mod route, and with this particular amp (Forte 4a), I've read it does better with more power supply capacitance (makes sense to me). Do I need audio grade capacitors (e.g. VH audio caps, etc) for this mod, or does this portion of the amp circuit not require such quality?
Thanks in advance,
