Almarg-The Power Supply to Analog circuitry, as well as Digital circuitry, comes from the same source. It is Direct Current from the Rectifying Stage. This Direct Current isn't Transmogrified if it is supplying an Analog circuit instead of a Digital circuit. How do you Transmogrify Direct current anyways? Jmcgrogan2 claims that no-one uses Tubes, fancy caps or resistors in the Power Supply to a Digital Stage as opposed to an Analog Stage. The point is completely bogus, since both Digital and Analog Stages both run off of the same power source, Direct Current from the Rectifying Stage! Hello, Tubes are used for Rectifying AC to DC to supply Analog and Digital Stages! My System does exactly that, and it is certainly not the only one that uses Tubes for the Rectifying Stage. Direct Current is not Analog based, regardless of whatever analog circuitry is being supplied by this direct current. If I must, I will supply a list of Manufacturers and their Model numbers that utilize Vacuum Tubes in their Rectifying Stages. I guarantee you that there will be more than just a handful. This spans Amplifiers, Pre-Amps, CD Players, Digital Processors, you name it! The issue was never Analog Circuitry, it was fancy Resistors, capacitors, and Vacuum Tubes! All of these are used in a Rectifying Stage to supply Direct Current to both Analog and Digital circuitry-FROM THE SAME SOURCE!
