Gearhead and I were discussing valve amplifiers and their design the other day. That got me thinking :-\ and I would like to know what you guys think of it. The design I am fine with and we, Gearhead and me, will still discuss this aspect further.
What I was thinking of is the output of the amplifier. I have an 18W in mind with a variable voltage regulator, or as I like to think if it, a “master volume” setting on it because as I was told a pure 18W valve is “insanely load”. ?
Now, I do not think I will ever play in any venue larger than our church. It is about the size of an average school hall. Does that mean that I will be wasting my time and money building a 18W and should rather settle for a 5W?
Here are my reasons for thinking I should rather go for the 18W.
1. If I understand it correctly, the first 75% of a valve amplifier’s range is clean and the last 25% it is in overdrive. Am I correct? If I am, I can turn down the VVR to get to the over drive quicker, or I can have a decent clean channel by turning it up. I see it the same as a powerful car. You can only drive 120km, but that extra “oemf” that it gives you if it can go to 220, can be very useful. Does this make sense?
2. If one day, I do play outside or a bigger venue, or just to irritate the neighbours :?, I will be okay.
On a serious note, what do you think?
