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.

If you are struggling to get the centre image balanced may I suggest-

.Try swapping left for right speakers and right for left and see if the imbalance is still there.One speaker might be faulty.

.Swap the tubes left for right and right for left and see if that changes anything.That will indicate if there is a faulty/low output tube.

If all that tests OK then you might need to change the balance pot for a different value.Any technician could do that.

Do the Chardonnay automatically ship with one set of input & output XLR?

Thanks,

I had some problems with my Cabernet when I got it, problems with hum, it ended with the pre being sent back to Mick for fixing,

When I got my amp back the hum had disappeared but unfortunately while the 6SN7 was working great, the 300b output only works as long as I don’t use the gain control, as soon as I engage the gain control switch I lose the left channel, therefore I can not use the 300b output to my satisfaction.

Not sure if it is a quality issue in production or it is shipment damage, have open it up and taken pictures of the inside but I can not see anything loose soldering or otherwise or out of place.

I think it is a bit challenging to buy from a small company and having it shipped halfway across the world.
