Does anyone know the fuse value of the LX500? I'm considering getting a SR Blue for it. The other SR Blue's I have used in other equipment greatly reduced the noise floor and increased low level background details.

According to the enclosed info sheet, the fuse is a T3, 15 amp, 250 volt, 5x20mm (small).
Never had considered "upgrading" any fuse, but since I haven't tried it, I can't knock it.
If you do, let us know if it makes a difference.

Re: the 6922/6DJ8/7308 family of tubes, one must realize that no current production tubes are produced using the manufacturing techniques and materials of the better NOS tubes (true for many tube types, unfortunately).  So even though many of the NOS tubes appear expensive, the improvement in sound quality over a current production tube is substantial.  Here are links to a couple of comparisons I have found
