Keep all leads as short as possible. Heat Sinks Double the number of heat sinks required for the Low TIM Amplifier. The power supply circuit diagram is the same as for the Low TIM Amplifier. The parts are the same with the following exceptions. T1 - The transformer should have either a center tapped secondary or two separate secondary windings which can be wired in series.
V ac rms for two secondary windings.
This should give a no load amplifier power supply voltage of plus and minus 85 to 93 V dc. Some transformers are rated at 115 V ac rms on the primary. The transformer I used in each of my two original Double Barreled Amplifiers was the Signal 230-6. I wired the AC line input to the 115 V tap. The Signal transformer was definately an overkill.
