Had a crazy idea for Emotiva tube amp.
Make it a bi-amp tube amp. You would have your standard L/R inputs (or integrated). Each channel would have two sets of tubes and two sets of binding posts. You would have a pair of el34 for the mid/highs and kt120/150 for your bass. It would certainly be a unique product. They would have to be level matched at the factory.
Unfortunately people with single input terminals would be left out.

Unfortunately people with single input terminals would be left out. Interesting idea, but I'd much rather use my XPA-1Ls for the low end and an El84 tube amp for the high. The horns in my DIY speakers are a 2-way system. The horns will do 108dB - 1W. The woofers run at 94 dB. That's a 14dB difference. In other words, if the low-end hit 100W then the EL84 amp would need to output about 5W. |

Surely it must have incandescent indicator lights?

There is an absolute dearth of low power monoblock amps available . . . Canary Audio is a good example of what is out there at $8700 . . . That's more 2 weekends of trackside support for me and not worth spending on a pair of monoblocks.
Technical requirements for an Emotiva Valve/Tube amplifier:
SET (not in parallel or push/pull) Triodes only
300B
Class A
Monoblock
Possible hybrid, i.e. solid state power supply with a stiff rail voltage of 600v
Auto-biasing
No Negative Feedback
Point-to-point
Silver wiring
XLR or single-ended
Cardas or equivalent connections
There is a large market for these amplifiers.
Audio marketing sells on wattage, like auto manufacturers sell on horsepower.
We all know that torque wins races, and horsepower sells cars. The same is true for amplifiers. If the first watt doesn't sound good, why should the rest?
cheers

Lonnie told me that the 300 watt Monoblock's that are making will be manual biasing. He said he thought everyone would enjoy playing with the sound of biasing to get some distortion out of them if that's what they want. I do want tubes that sound very tubey and hope they do.

Details like that lead me to wonder if they are closer to release? Maybe? Yeah, I know. I'm totally speculating. Like usual. |

Been working on a couple of different models, mono-block and stereo. Right now it does have an analog meter, old school style with a twist (what else would you expect).  Overall its very old school with a few modern additions like auto rail selection, soft start and a few others. But from what you will see, it will be very much a tube amp. All the modern electronics will be tucked away and out of site. Oh and the electronics have nothing to do with the audio, they are strictly there for power and protection. I am not quite ready to give out any other details yet, but they are really sweet amps. I will give more a little farther down the line but this is about all I want to say right now. Lonnie |

"What would you like to see in an Emotiva Tube Amp?"
Um err... Tubes!

I thought that it was already stated that Emotiva was working on monoblock tube amps in the 200W - 300W range? I would swear that I read that on a thread, maybe even this one.

An important consideration with tube amps is said to be that they lose their sweetness in megawatt versions.........., as well as all the heat and tube replacement costs, when output tubes run in the area of $50 each.
Tubes for comfortable volumes, TONE and imaging, s/s for head pounding, home theater, and "rock" music.
Dons flame retardant suit........

He said he thought everyone would enjoy playing with the sound of biasing to get some distortion out of them if that's what they want. I do want tubes that sound very tubey and hope they do. The first time I posted the information about the Monoblock being 300 watts there were comments like, that is impossible unless this or that. I don't believe Lonnie would fib info about an Amp that he his working on. The Man is proud of his work and there is every reason for him to be. He has been kicking some butt's with the one after another great Solid State amplifiers coming from Emotiva. Just because other's make Tube amps and this will be a first for Dan and Crew, what says they can't kick butt's with there Tube amps ! |
