Wish I could tell you. I have not found a source, either. Mine were on loan from a friend.

That's the sound of the other shoe dropping...

finally dropped in the GE 7044, and these tubes absolutely added some flesh. i also removed the herbie tube dampers i had on my tubes, i think they were sapping some of the life out of the sound. i dont like boom or loose sound, but i also think some natural bloom is a must. anyway, i wonder why people are so enamored with the tungsols... they are definitely tighter and leaner. i guess it depends on the system, but i like the GE's better. now, off to try to find some sylvnias gb 5687. :)

Yup. It's stunning what Sylvania GB-5687 tubes do for the SWL 9.0SE. Other than being plentiful and inexpensive, I can't think of any other reason for the TungSol 5687 to be used so extensively in the Modwright preamp.

hey tvad... so, how much better are the sylvania's over the GEs? what would you say are their noticeable differences?

The Sylvanias have a sweeter top end than the GE 7044, with excellent extension, balance, and no hardness, etchiness or glare. IMO, the Sylvania GB-5687 tubes are a significant improvement over the GE 7044 in the SWL 9.0SE.
