Vin= SSHV input / Vout= SSHV output


Because i am on vacation, i had the time to listen to two other tube rectifier i have.

The question, if there are still differences in sound with different tube rectifiers and the SSHV in between, is

YES !!!

Till now i used the Bendix 6101, a very nice sweet and soft sounding rectifier.

After i roll to the SED Winged "C" 5U3C (5U4-G) Black Plate rectifier,



...someone lift a invisible curtain...



Much more precision in the mids and highs and the soundstage open up in all directions.
Jesus, in comparison the Bendix sounds much to soft!

The Mullard GZ37/CV378 Coke Bottle has also the qualities of the 5UC3 Black Plate,
but is a bit softer sounding.

The only disadvantage of the 5UC3 is, no soft start... But hey, there are solutions for that on the planet!

    Hi Francesco,

    because it sounds best.
    Sure it has no softstart, but i don't think thats a major problem for the small double triodes

    so the reference PSU provides 140v for the tubes and ~ 14vdc x2 for the digital circuits?

    No.

    The tube rectified B+ voltage is ~185VDC with two taps (SSHV input voltage for each channel).

    Additionally i have 4 SS rectified voltage lines. 3x ~15VDC and 1x ~25VDC (SSLV input voltage).
