I recently jumped in on a drop for the Aune T1 MK2 headphone amp, and as I was reading more about it I ran across the following post on reddit (there is a very good chance that this guy posts in here too, I'm sure):
quote:
Dude, this is not a tube amp. This is a solid state amp with a decorative tube.
If there is no high voltage power supply, then it is not a tube amp.
Here, have a look at the 6922 datasheet. As you can see, it is designed to run at 100V-200V. This amp does NOT supply 100V-200V to the 6922.
Tubes have a filament, so they need a second voltage supply in addition to the the main one. But filaments only need 6V or 12V (generally, some have different requirements). The 6922 needs only 6V. So the amp provides 6V to make it light up and then solid state does all of the amplification.
It's like sticking a vacuum tube on the hood of your car, supplying 6V to make it light up, and then claiming that your car is powered by a vacuum tube. Which is just as much ******** as these phony "hybrid" amps are. Don't be a sucker. Don't buy it.

I'm a noob when it comes to what is physically happening inside of an amplifier; can anyone enlighten me as to what he means here? Is any inexpensive 'tube amp' essentially a ripoff?
