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.

Does your Cabernet have a mute switch and, if so, is it active on the 6SN7 circuit?

If you answered "yes" to these questions, you can flip the mute switch prior to powering off any equipment and you'll avoid the thumping sound.

It has, but only on the 300B output.
That is the only small disappointment when buying, I had the understanding that both outputs could be adjusted or at least the 6SN7 output as that was the reason for buying the Cabernet and the 300B would be a bonus.
Maybe Mick should make other buyers aware of that.
I have only listened shortly at the 300B output, will try to get a better listen over the Easter holidays

A few days after my last post, my Cabernet started outputting a loud hum in both channels, can hear it from the kitchen 7 meters away when it is at the loudest, have tried everything I can think of to get the hum away, but to no avail.
After emailing Mick, his conclusion is that the power supply must have gone bad.
Mick is sending me a new power supply.
Unfortunate that this should happen, but that Mick right a way offered to send me a new power supply is encouraging and hopefully that will cure the problem.
Anyone else have any problems like this ?
