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. Are you assuming? I was told by 2 Emotiva people that they would definitely debut a mono-block at 300 wpc running KT-120s. I was also told they'd release it in late spring, give or take. Edit: I was told this about the 2nd week of November. 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. Poppycock. I really wish you could hear my 350 watt Carvers. As sweet as a Chocolate Sundae. Heat? I've only got 2 more KT-120s than you do and they're only running at 100 millivolts. There is no more heat than my Jolidas that had 4 KT-120s outputing 140 wpc. $50 replacement costs? Keep in mind lot's of guys are running KT-150s at over $90 each. Uh, Audio Research, Conrad Johnson, BAT and Cary for starters,,,,,,Entering another league. Yup, those are the guys that are going to get there butt's kicked ! Definitely. Like all the other products, Emotiva's tubes will be kick ass! Keep the faith.... |

That's my point, at $50-$90 per tube, how many here will be delighted with that? I am, but know the turf.

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 I think you'll be in for a personal disappointment. They won't be SET. Almost certain that they'll be push pull. No 300B. Fairly certain they'll run KT-120s and probably be KT-150 capable. Little or no class A, Class AB only. No auto bias. 20db feedback. Definitely no point to point, no silver wiring, and no Cardas connectors. Any of this on an Emotiva amp? Never. Thank God. XLR and RCA has a very good chance. Would that be enough out of your list? It would work for me... Peace |

I hope you realize that life....at 100mv bias, I have my doubts, unless you only run them 15 minutes per day.
Mine are run at 60mv, in a nice spot for the KT 120 in my amp.
but of course, it depends on the value of your cathode resistor.

My Cronus is biased at 35mV, but they do run 100 pp... Any clue how long they'll last? Rogue thinks 3000 hours.

No------------ tube amp from Emotiva would not sell well
Media player would sell well---wake up

No way to tell unless you know the value of the cathode resistor......it's the bias current, not voltage that's important. my monoblock amps develop 140 watts from four KT120s, meaning they're conservatively designed. I like Rogue, they're made not far from me. |

"What would you like to see in an Emotiva Tube Amp?" Um err... Tubes! And a delivery date? |

Audiobill,
If I remember correctly we are practically neighbors. I'm down in West Brandywine and I believe that you are near where 100 and 113 come together.
I went up last year just before thanksgiving and had a tour. Got to have a brief chat with Mark. In fact, he told me about delving into digital which is now in the new pre-amp.
I'm thinking that 100W out of 2 KT 120 is probably a bit hot. I think that they are rated up to 60W each.

Hi neighbor! I do think the larger Rogues are a bit more conservative, but the Cronus is well loved. Quicksilver is another high value US tube make that is excellent. But, for $2,250 per pair, I can't beat my M-125 kits. pedrocols just built a pair too. Made in US ? How about on my kitchen island!!!  |

Mine are run at 60mv, in a nice spot for the KT 120 in my amp. but of course, it depends on the value of your cathode resistor. When I get home tonight I will see what my carvers sound like at 60mv, usually have them between 90 and a 100. Never had them that low. |

That's $1,080 for a retube, all those who are lusting for that much power!!!!!
However, must sound so powerful!

I looked the Carver up, and with 725 volts on the plate (!!!!!), 80-100 mv is suggested for best sound.
That's a lot of plate voltage!

Good deal.
With bias, there are all sorts of measurements, some for all tubes together, some for pairs and some for individual tubes.
The 60mv I quoted is for each KT 120 over a 10 ohm resistor for 60 ma.
YMMV!
