to retube or not

thanx bradz...actually, i'm using the x-10D with a MF x-psu power supply.

Are you using the supplied factory power adapter? If so, I'd suggest changing to a 12 vac @ 4.5 amp adapter (part # 56-821) from www.hosfelt.com for $7.95! After removing the factory power supply and using the hosfelt power supply in its place, I was impressed with a much fuller sound, more dynamics, and a cleaner sound. Another tweak you might want to consider would be Herbie's tube dampeners for your tubes.

thanx david_berry and rcreations. to david, the tubes to be replaced are the musical fidelity X-10d tubes, which they say are not that good being jan philips 6922s. i use the x10-d between by rotel 951 and receiver. i posted this thread to know if anyone had any experience replacing the tubes, and getting the sonic improvements. hope this clears up matters. thanks......

i replaced with siemens and liked the change. go with what tubes you prefer in other units. (in my case i liked the siemens in the pre i had at the time. its a tight squeeze replacing but can be accomplished with patience. kurt

In what equipment are these tubes going into?
