The problem is the cost - in particular the transformers.Yeahh well that's the thing. That's why I want to build one, and stay away from those expensive kits. I could probably make the power supply but that would be overkill as I don't have the tools but I expect it to be the most expensive piece of the puzzle; but could I take a psu from another thing/machine ?
Even/Odd harmonics:Dunno why, but musicians seem to like the 'character' that adds.
Adding harmonics to music is distortion, it is not natural, it is awful. A vacuum tube and a transistor both cause even harmonics and both types in the push-pull output stage cause odd harmonics. But the vacuum tube amplifier has an output transformer that has phase shift so not much negative feedback can be used.Even/Odd harmonics:
Tube (valve) amplifiers make harmonics where there are already harmonics in the music. It sounds 'natural'.
Amplifiers should never be over driven. They should have some "headroom". Aren't the ceilings in your home much higher than your head?When a tube amp is over driven it distorts 'softer' than the hard clipping of a transistor amp.
You are darned right! But I have heard very good sound from vacuum tube hi-fi amplifiers, not from guitar amplifiers.I should know better than to talk about audio, just under a post from AudioGuru.
But hard clipping can be avoided by diligent use of compression/gain control. That could also reduce/prevent harmonic generation. I'd bet wiser heads than mine have already looked into this. I'm sure that with enough design effort a solid state amp could be made to give an output audibly indistinguisahble from a tube amp.When a tube amp is over driven it distorts 'softer' than the hard clipping of a transistor amp.
Why would you want to lower the quality of a transistor amp to try and make it sound like a valve one?.I'm sure that with enough design effort a solid state amp could be made to give an output audibly indistinguisahble from a tube amp.
Personally I wouldn't. That's just for the folk who prefer the distortions of 'valve sound'.Why would you want to lower the quality of a transistor amp to try and make it sound like a valve one?.
I thought that's what we are talking about here. The OP refers to a 'fellow guitarist'.Fair enough for guitar amps
Isn't that simply treble boost ?Adding energy at the harmonics, increases the sound level, sounds louder
