    Cool.. it Will be interesting to see how your impressions hold up or change over time.  Curious, how do the 650 compare with the Q701 powered by this amp?  thanks and enjoy

    Night & day....the HD650 wins hands down....so much more synergy.
     
    The Q701 has now been sold  [​IMG]

    Sweetness...
    6080/6as7G tubes respond WONDERFULLY to output transformer coupling and paper-oil output caps.  They are using the Hammond119DA (again).  A proven winner, for all impedance loads at the wattage levels we are talking.  Output caps are chosen wisely at 400V / 35ufd.
     
    Looks like another solid design using a great sounding tube set.
     
    [EDIT] looking over the schematic, I wonder what kind of resistor they are using on the output tube power side?  It says 3K-20Watt.  This can be a problem area if the component is not spec'd properly and the chassis does not vent / dissipate the heat.

    The power supply on the Super 2 runs really hot.
    I believe the chassis is used as a heat sink in spite of the vents....

    My 5751 Sylvania triple mica black plate is going bad.
     
    I am going to grab a new one.....anybody have any suggestions for a few more tubes to consider.....something with loads of detail would be nice.
     
    I guess, if I have too.....I can go thru this whole thread.

    I am going to grab another 5751 BPTM
     
    I also want a nice 12AX7 for my HD650.....it will really like the extra gain.

    I just bought a Genalex Gold Lion 12AX7 with gold pins.....cant wait to give it a try with my HD650
     
  14. jaywillin

  15. whirlwind
