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.

Yes, I am not a fan of the biblical cord between power supply and pre, seams unnecessary stiff and unwieldy, a softer cord would be preferable, will check both connections if, or probably when the hum comes back, as I suspect it will.
Now I hear only a slight hiss from the speakers, but I have not tried it with the 6SN7 output since the hum disappeared, unfortunately I am swamped with work all week and probably weekend too, so no testing until sometime next week.

There is a big difference in sound between a standard 300B and say a TJ Full Music meshplate.Almost like a different preamp.With the meshplate you get beautiful airy treble,much better timbre and a much more holographic soundstage.If you have heard the difference between say the really good Dynaudio speaker models and the next tier down it is that sort of difference.The difference between good and great.

On the Cab Dual Mick recommended to stay away from the mesh plate tubes, was it the current draw?

I have used meshplates in  my 300B single Cabernet for years with no problems.

Sure you can use these, I was just talking about Micks recommendations, specifically not using a tube using more than 1.5A of heater current
