Tube rolling experts!!!


Hi guys,

I am looking for advise based on your experience with these particular tubes in my components.  

I own a Raysonic CD128 since 2009. The player came with 4 Russian 6922 EH tubes. I don't know what's the average life span of tubes or when they start to deteriorate from their optimal performance. The player is used sparingly, may be no more than 500 hours over last 7 years. Is it time to replace stock tubes?  

The second components is Modwright Elyse with Phillips NOS 5R4GYS Rectifier and Tungram PCC88/7DJ8. Is there anything else out there that I can experiment for substantial boost in sonics?

I am after that lush midrange and extended top end. More air around the instruments, but stay away from anything that overly 'bright'.  

The associated components are Krell Evolution processor and Modwright KWA150SE (both solid state). 

Thank you for your time!

The tubes in your Raysonic will last many more hours before they require replacement. At the rate you use this unit you may never have to replace them. However if you want a different tone than afforded by the EH’s it is easy to change by using different tubes. I use JJ 6922’s in mine.
