Is Audible Illusions Still in Business?

[sstcobra]

I have emailed twice and called 3 times with no response. Are they still in business??? I am the owner of a used Modulus 2D Preamp that has an intermittent whistle in one channel. After opening the unit I find 2 Chinese GoldenDragon tubes and 2 Sovtek 6922 tubes with a date code of 12/88. The manual calls for 4 6JD8 tubes (which cross to the Sovteks).

Can someone recommend a dealer to provide quality replacement tubes for my preamp? Also, if the tubes are not the issue, is there someone out there who could troubleshoot this unit?

Thanks....Gary

hi Gary, from what i have read the modulus preamps are extremely sensitive to microphonics. if you look at the tubestore . com website they recommend certain 6922/6JD8 tubes for this preamplifier and also warn you not to use certain other tubes because of the high sensitivity to microphonics. very nice preamp though.

You might check with upscaleaudio.com. They have a huge inventory of tubes.
