Supratek Owners Thread


Greetings All - 
It appears that the 26-million-plus view, multi-decade "Preamp Deal of the Century" Supratek thread has been removed. I'm not sure why, but suppose there must be a reasonable explanation.
In any case, on that thread I recently asked whether there might be interest in a "Supratek owners thread" and received some interest. 
The purpose of this thread is for Supratek owners to share the details of their system, ask questions, share information about any tube-rolling they have done, and so forth.
I'll kick us off here with a few details about my system -
ancient Linn LP12 with Ittok arm, Dynavector 17D3 cartridge into Cortese LCR phono stage
Power amp is a fully serviced Innersound Electrostatic amplifier
Quad ESL63 speakers (not USA monitors) or JBL 4430 studio monitors
Digital sources are immature and evolving - ancient Fostex CR300 cd player/burner
DacMagic 100 DAC
Nordost Blue Heaven 75ohm interconnect
Due to the fairly long lengths of speaker wire required in the new listening room, speaker wire is Belden 12 gauge wire designed for low-voltage outdoor lighting systems. 
Next steps - dedicated circuit, new power cords, new interconnects, new wires.

Thanks,Jack. The reason I asked is because looking at the photos Mick has posted currently on Agon, it’s not apparent: https://www.audiogon.com/listings/lis9d477-supratek-audio-chardonnay-tube#&gid=1&pid=2. Does what you have, assuming you do, look different? And btw, what’s that knob on the top left in front of the tube do, if it’s still there?
On mine that knob is on the right but it is the balance control.  The sensor is just barely sticking out the bottom in the center from the chassis.  You would have to look real close to see it which you can't from that photo. The knob in the center back is gain and the two switches are manual mute and one defeats the gain control.  
One more thing to add is that Mick estimates the PSU to be 18 lbs and the preamp 9 lbs (ships at 16 kg).
