Description
This regulated power supply is identical to Kit#7 except that rather than using the 12X4 rectifier tube to give us raw high voltage B+, it has been replaced by a diode bridge. High voltage B+ for the preamps as well as DC filament for the tubes are both regulated using solid state voltage regulators giving 100% stability and super low noise performance. It comes complete with its own two power transformers, both of which fit on the PCB. Quality metal film resistors, film and electrolytic capacitors are standard with this kit. The PCB is manufactured to FR4-TG standards with ground planes on both sides to improve screening as well as component screen printing to make assembly easier. A set of assembly instructions is also include.
Please note that the photos are a general indication, and component colors and style can and will vary.
An important note about using this regulated power supply: it will NOT work with our clone PC5 & PC6 upgrade kit, or original Dynaco circuits, due to a quirky way that Dynaco tied one end of the phono preamp tube filaments to main power ground, which does not agree with the way the DC filament regulator operates.
