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 hear a faint hum coming from the power supply also, only hear it when listening close to the unit, not anything I worry about, plan is to move system to an other room with dedicated mains line, will see if that changes things.
Well received an email from Mick, According to him quote ' its nothing to worry about, you might find it depends on the time of day, the mains voltage etc. Its very over engineered and very strong transformer'. So am not going to worry about it. It is beautiful to look at and it rocks.
Hi All,
I have a Supratek Cortese preamp in my system for a couple years now, 2018 build.  I recently had an issue with it that required repair.  I want to let everyone know that Mick really stands behind his products.  The repair was covered under the lifetime warranty.  I just had to send it to Johnny Slate, Mick's US tech.  Johnny was excellent to work with and now it is back in my system singing again!  Now that's customer service!
Has anyone thought of or changed the fuse on Cabernet to a higher end fuse? I am thinking of doing it. If you have changed it then can you list it here and the changes you noticed. Thanks.
