Another friend, another amplifier. This time a 3020A. Doesn't quite match the schematic I found on the 'net (which is for a 3020i so it figures).

So, to re-cap a NAD 3020A you need:

• 2 x 0.68u 25V
• 4 x 1u 25V
• 2 x 1u 50V
• 2 x 4.7u 35V
• 2 x 10u 25V
• 6 x 47u 25V
• 12 x 47u 10V
• 2 x 47u 25V
• 4 x 47u 35V
• 2 x 47u 63V
• 2 x 33u 25V
• 2 x 100u 10V
• 2 x 220u 6.3V
• 2 x 330u 35V
• 2 x 1000u 6.3V
• 2 x 2200u 6.3V
• 4 x 2200u 35V
