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.

I have been trying out a lot of different tubes in my Cabernet, ranging from RCA 12sx7, TS round plate, 6f8g from Sylvania and Raytheon, Sylvania "bad boys", 7n7, etc. 

My tube rolling mania got the better if me and I bought some adapters that allow me to use a pair of *j5 instead of a single *sn7. Got them from a guy in Bulgaria that does great work.

Anyway, started with some Sylvania 12j5gt with round plates. Wow! There is a level of clarity and openness now that I hadn't heard before. Trawling through some forums it sounds like even the inexpensive metal version sound great.

So if you'd like to try upping your tube rolling game without breaking the bank, try some 6j5 tubes! I also highly recommend getting Mick to install a 12v option on your preamp if you order one. It opens up a lot of possibilities.

Can someone measure the dimensions of the power supply for the Cortese? I need to make a shelf for the power supply, my rack is full. Just a shelf for the preamp itself. Thanks for any help.

@skypop the chassis for the power supply is the same size as the preamp itself, so about 13.5 inches by 13.5 inches. Roughly.

In terms of height, with the rectifier I'm using (large shouldered tube), the power supply is about 10 inches tall. I have about three inches of clearance between the top of the 5U4 and the shelf above it.

Thank you very much, this is going to be sitting on the floor next to my rack.

Good idea @skypop . Wonder how long the umbilical cord is? Wouldn't want my linestage 2 ft. off the ground. 

Thanks,
