Douglas, a lower voltage supply. But, may draw more current, right? At least compared to a (-40 to -60 VDC) bias supply --- for the same amount of wattage.For -15 VDC, at 1/2-watt = 19.2mA. Build a 50mA-100mA unit?
At 50-100mA, how much does background noise in the bias supply need to be addressed? Versus a 15-20mA bias supply. Prolly need a choke and a full-wave bridge.
Thanks
