I suppose the original was meant to be used with a VERY low impedance power supply, not something knocked together from a full wave bridge rectifier and a 1000uF smoothing capacitor. If your reference has a section on power supplies, try doing what it says. Otherwise, try what vk6ro said.

Or your could find an amp design by somebody who doesn't have such strong opinions on why everybody else is doing it wrong...
