More pics are needed.
Not only is the cap rating low, but it's also only 50 volt. I could be incorrect about this but from what I understand about class AB amplifiers (which I believe is the topology of the amplifier in question) is if the amp has one transformer it has one power supply. The power supply consists of primarily a transformer and capacitors (as well as resistors, fuses, relays and such). No particular "channel" gets a cap or it's own capacitor bank. One cap gets used for pushing, and another for pulling current. Again, I could be wrong (it happens often
).
Your receiver would not support this. Something like the Yamaha RX-V661 or RX-V663 would be great. If you are on a tight budget you might try and find an older Pioneer VSX-816 which was very well received for it's features in it's price bracket (basically the cheapest receiver to have preouts). Unfortunately Pioneer's more current 800 series AVR's lack preouts and that is reserved for the 1000 series only.
