Mikä on hyvä ja huono on tietysti makuasia. Alla VHT:n porukan näkemys, minkä kanssa mä olen hyvin pitkälle samaa mieltä.

"High power output: KT88, KT90, 6550
 
Although not widely used in the guitar amp industry, we find them to be ideally suited to players who want power punch and articulation. They are used in a variety of configurations, mostly in pairs and quartets and in some cases, sextets. They are capable of delivering 100 watts per pair and this is the typical application in which they are applied at VHT in the Two/Ninety/Two and Twenty One Fifty power amps. Quartets of 6550's are used in the Pittbull Ultra-Lead and are more conservatively operated at about 60 watts per pair. Because of the high output capability and efficiency of these tubes, amplifiers that use them exhibit a wide dynamic range, lots of low end power, crisp attack and to quote Guitar Player Magazine "miles of headroom".
 
Medium power output: EL34, 6L6
 
These are the standard bearers of the majority of the tube guitar amp industry for the last 30 years or so. Typical output for a pair is 50 watts. We use EL34’s in the Twenty One Hundred power amp, Two/Fifty/Two power amp, Hundred CLX head, Hundred/CL head, Fifty/CL head, Fifty/ST head and Fifty/Twelve combo. EL34’s are harmonically rich sounding tubes with a strong upper midrange which complements guitar voicing very nicely. When driven hard they exhibit a smooth transition into distortion while maintaining clarity and good tone quality. All VHT amps that use EL34’s can be switched over to 6L6 operation. 6L6’s generally sound a little cleaner than EL34’s and tend to have a bit more beef in the low end as well as more bite on the top. Some players prefer the extra clarity and punch of these tubes. Others just like them because they are used to the 6L6 sound. We will ship any of the above models with 6L6’s installed by special request. However, we prefer the sound of EL34’s in our amps and these are what the above models are shipped with as standard equipment.
 
Low power output: EL84
 
This great sounding and economical tube, has had quite resurgence in popularity in recent years due to its increased availability. Typically used in quartets and run in Class A mode, they are good for about 30 watts or 40 to 45 watts in Class A/B. They basically sound like a small screaming EL34 with a rich fat midrange voice and great distortion tone. We use this tube in the Pittbull Forty-Five series heads and combos."
