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.

Any of you guys using solid state Power amps with your Supratek pre’s ?

Tubes,.. all the way.  Only SS component currently in is the hybrid PSA-BHK Pre, soon to be replaced with the new Grange beast that Mick is looking to put back 'on-line'.    Will have a  DHT and 6sn7 circuit that can be flipped between along with the LCR phono.  He briefly mentions it in his latest blog post.  Due ~April/May,..  Amp wise I switch between a Decware SE84UFO 25th Anniv.  and Gerus 300B.   Never personally cared for the sound of SS or PP tube circuits.

Shibui,..   I would imagine that the only tube you should pull is the Rectifier which will sever the B+ voltage and reduce the risk of a short when trying to measure.    If you measuring the heater voltage,  all the tubes in that circuit need to stay in place to provide the 'running load' to the transformer.   When you start removing tubes,  the load changes and the heater voltage will start to vary a bit, increase.   Best to talk with Mick again if you have not though.

HighStream,  that was my impression from Mick.   That this new circuit really narrows that gap between components and really just makes the perceived change in components just different not necessarily better.
