Ik doe niet aan tube-rolling. Ik heb erop zoals de bouwer het bedacht heeft. Merken buizen zegt mij wat klank betreft niet zoveel, ik heb nog geen verschil gehoord. Er zit wel verschil in levensduur en betrouwbaarheid, Siemens, Philips, Sylvania ( USA) en RCA zijn bij mij favoriet.
Eens buizen altijd buizen.

Dit is het advies van de fabrikant van mijn buizenversterker:

"ProLogue Premium, ProLogue Classic, and discontinued models ProLogue One and Two, DiaLogue One, Two, Four, Five, Six, Seven: The two small tubes in the very front/center are the gain tubes, and they are very much in charge of how the amplifier is going to sound. The tubes flanking the front two are the driver tubes, and they will also make a change but not nearly as great. So concentrate on the front two. See photo below":



En voor de eindbuizen geld:

"If you want to go to a "larger" tube like a 6550, KT88, or KT120 the result may be a little more "pop" to the music, and while the bass may appear to go a little deeper, it will not be as "round" as an EL34. In KT88's the most common is the Electro Harmonix which is great, the Mullard re-issue and Gold Lion re-issue which in essence are the same tube and are superb. And then the Tung-sol KT120 which has even more "pop" and because we run them so easy, the tube may outlive you"

Nog wat wijze woorden:

"Don’t buy tubes from just anybody. Sadly tube manufacturers don't throw away anything if it can somehow be sold, so every tube will end up in someones system. Even the weak ones. A brand new Russian-made Gold Lion, Tung-sol, or Mullard re-issue could be brand new in the box, factory fresh, and have only 10% of its life left. Tubes are not like buying tires. Every single one measures different. If it’s lesser quality, it will go to sellers that deal in that type of product, and they sell it for a lower price to the unsuspecting public. You could save 10% on the price of the tube, and it will have a life that is 30-50% shorter. Or damage your amp. Not smart"
