D3A Phono Build

@TechShop - Powered up SSHV board... changed Heatsinks.. Power Resistor 470K to 1K/20W - Set output voltage to 220VDC @ 5Kohm load - 6.3VDC okay Heatsinks for both IRF9610 and IRF840 continue to be hot...Looking at changing to a bigger 4"X3" aluminum plate. Need to check all voltages as per the note Things to do : - Extend 6.3V secondary winding - Power switch on Front Panel; drill hole - RCA connectors - Shielded hookup wire - Silkscreen rear panel
