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.

@sim_audio_nerd I'm interested in ordering a set for under my Cortese. Did also try a set under the Power Supply? Which ones are you using,Thanks.

@skypop I did..initially for the preamp unit and then the power supply unit also. I am using the CS2s I believe..

Hi to all the Supratek owners,

Does anybody know how to make the gain switch on an older Chardonnay unit the right way without losing quality? 

It's a modified Chardonnay with KenRad 7193/2C22 and Western Electric 350B  tubes, and Bendix 6106 in the power-unit.

When playing on maximum power, the attenuator is between 9-10 o'clock. Zero is at 6 o'clock, and max is at 4.30 o'clock. 

I geuss that -6dB will do the job.

Thank's and greetings from Holland! 

The gain control (if we are referring to the rotary knob either on the back or top/rear) Is simply a vol. pot or resistive divider on the output.   Best case is to leave it at 100% ie,. Not in the circuit.   Its is mainly used to help integrate amps that have a very high sensitivity when used with sources that have a high nominal output and thus do not allow much main vol. knob rotation.  I personally prefer the main vol. knob operationally around the 9-11 oclock range.
