Received my Grange in Black/Chrome. I havn't had te chance to listen as my systems are tore down for the time being.
I did mangage to inspect it after it arrived and it is a thing of beauty.
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’ve been battling a noise issue. Adjusting the volume was incredibly scratchy and there was a background grittiness that was annoying me. Finally traced it to one of the 6l6gc regulator tubes. With cleaning I had managed to narrow down the noise to just one channel. Then when I swapped the signal tubes the noise was in the same channel. I never considered the regulator tubes because I never touched them. The preamp came with them already installed and I never used a different tube. Anyway, I took out the one on the right, cleaned the pins and now there’s no more noise! I wonder why that tube got noisy, very strange. |
@isaacc7 Glad you were able to eliminate the noise. I recently used a Dremel, with soft buffing wheel, to clean all the tube pins for my Don Sachs linestage and VTL ST150 amp. A huge improvement with the old stock tubes in the linestage. Much sweeter and purer high frequencies. The VTL tubes are only ~5 years old, and there wasn't as much improvement. Thanks, aldnorab |
