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.

"Sounds like the input switch was in the wrong position of faint sound was coming through."

This is exactly what I was thinking. 

Note: be patient as you test the various input pairs and the selector switch. It can be a little confusing - at least it was for me. For instance, viewed from the front, my LCR phono stage is at the 10 o'clock setting, even though the input is the furthest one to the left (looking from the back). And so on.

There's something going on.  I got it to sound a little better and then it reverted back to a thin/faint sound.  I'm going to try a different source tomorrow and eliminate one possible issue.  It's gotta be something simple and I'm optimistic I'll get this working.  Can't wait to hear it.

Yes. Trying different sources. CD player. DAC. phono. Cassette. All of them. Get a cassette playing, a CD playing, stream something through your DAC. All at the same time. Keep the volume at 9 o'clock while you switch between the sources. Read the owners manual. Tweak the gain control. Try the switches. I concur it's *probably* something simple. 

Please keep us informed. We're all on your side.
