Or the best thing, a change of valve brand can make a lot difference in an amp, American, British, Chinese, Eastern European, there are hundreds of different types out there and they all have their own sound characterists, I have a THD BI-Valve amp, which alows me to mix and match preamp and out put valves, and simply changing a pair of Svetlana EL84's for a pair Harma valves, or even mixing the 2 (dont try this on a standard valve amp) has a subtle but definate difference in tone.

I agree totally (and I was forgetting you have one of those nice Bi-valves, Lee). My little point was that, sometimes, a tech may do you a "favour" and replace your power valves. Of course, they wear out and this has to be done, but some nice old tubes/valves can fetch a fair bit of money in useable condition.

I took my amp + cab in to a firm because of a terrible, farty noise. They handed it back (several weeks late and after two pointless journeys) and told me "we've put brand new Svetlanas in, mate"

I had a shudder. What about the Mullards? "Thrown away", apparently. The fartiness was still there but I sorted it when I replaced the offending speakers. The Svets sounded rubbish and I can't help thinking that a needlessly replaced quad of Mullard EL34s might have been quite useful if the people hadn't actually "thrown them away"

If your amp's already fitted with the usual Russian/Chinese valves; disregard the above. If it's got British or American glassware, keep an eye on sudden replacements for dubious reasons.

with RMS output of amps, you have to remember that wattage is measured in a non-linear scale, therefore a 100w amp is only twice as loud as a 10w amp
