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 it's "bloom" you want, Mick's creations are hard to beat. Any music passing through my Grange sounds just "grand" and very intoxicating (same preamp-stage as the Cortese). For two months now I have burned the night oil with this extraordinary instrument with all musical genres and analog as well as digital sources. In my opinion, a Supratek preamp is a final purchase.

Anyone take delivery of a Supratek recently?  

Originally ordered a dark brown wood/chrome Chardonnay and ended up upgrading to a Cabernet 6SN7 since Mick had one available to ship sooner.  Might have been a cancellation…don’t know.  Mick mentioned he was having a very difficult time getting new tubes and said he was sending quality NOS tubes from his stash.  I received Radiotron (RCA Australia made 50’s-60’s) 6SN7’s, Russian made 6N3C’s 90’s?, Russian 5U4C 90’s for my set of tubes.  Curious to hear what tube set any of you received?
Also, would like to hear from any Cab 6SN7 owners on what tubes you are using or prefer.  Thanks

The Russian military tubes are pretty standard for him when he can get them but the NOS Radiotron's are an upgrade from the normal.  The 6SN7's should be fine as are the the Russian 6L6's.  I would look for a NOS rectifier though as the first swap.  They are getting more and more expensive but a good one should last you many years.
