Gorgeous sounding preamp, made by Oliver Sayes [sonic-oli ] using the 01a directly heated triode... Built in 2 separate chassis (one for power supply and one for signal for quiet and vibration free operation) and connected with high quality umbilical cable. If you haven't heard a good DHT preamp you owe it to yourself to try it!
Preamp has 3 inputs and 1 output with high quality Alps volume control.. Very low noise thanks to the current regulated filament (courtesy Rod Coleman) and the gyrator anode load (courtesy Ale Moglia) see Bartola Valves for similar implementation of the filament bias concept. Easy end user adjustment via top mounted test points and control.
Really sweet looking/sounding preamp...Comes with extra 01A tubes..Shipping is a flat rate $75 for three boxes in the Conus,,Paypal;fees paid by buyer...Please see my feedback on audiogon and Ebay as Pianopig for purchase assurance..
