Doesn't that seller post here?

The jacked up board reminds me of Curcios work. Does AVA build them that way now too?

The custom socketless chassis is pretty nice.

Yeah--come to think of it, the username does look familiar

Yes, that is an Ultimate 70, built in a new style Triode Electroinis chassis. Looks like new.

That's an old soundtastick chassis. Nice chassis, but it's not stainless. The Triode chassis is not silk screened and has a IEC cutout for the power.

Incidently, I will be listing 2 Ultra 550's with a Fet Valve Phase Inverter on A-gon....I'll let you guy's have 1st shot and discounted price at this Awesome HI-Power system if interested,,,,,

Hi Mel,

I noticed you droped your price on your Ultimate 70. So why do you need to do that? Probably because the market is real soft, there is other competition out there and a handful of other reasons too. But, in my opinion, most people that look at the your auction that know what a Dyna ST70 is, have no idea how really good the Ultimate 70 is.

Good luck,
Dave

That is a bargain.

It *is* a bargain. Wish I could dump my current tube-amp and pick it up.

The U70 amp described above was built by my prototype technician, but as a favor to this seller, not sold by or through AVA itself. Thus the AVA warranty does not apply.

It should be solidly and correctly built and have the last "wire switch" update. I do not know the origin of the chassis used, but definitely not one that came from us. I also do not know the source of the power or output transformers, but that seems to make little difference in the performance.

Right now I am happiest with the Electro-Harmonix big bottle 6CA7 tubes in our tube amplifiers. This unit appears to have JJ EL34 output tubes, which work well too, but to my ear are a tad brighter sounding.

The $995 asking price is fair. We would ask that for a U70 factory wired into an original Dyna St-70 chassis in good conditon.

Note that for best long term tube and component life, run the amp with the cover off unless there is a risk of children or pets coming into contact with the very high voltage on the exposed audio circuit board. Be very careful regarding that.

Regards,

Frank Van Alstine

Brian,

It's not an Ultimate 70. It is the older Super 70i.

I had a Super 70i, which Frank just upgraded to a U70. The Super 70i is a good amp, but there is not any comparison to a U70.

Ever since carusoracer lent me his modded Jolida for a week I've had a hankering for some EL34s. Speakers do well with a tube amp so I'm expecting good things. Mel (who's been a mensch) tells me this unit has the latest wire mod thingy doodle mabob.

Thanks guys...extended review? depends how much beer I have on hand. last time I did a long write up I was flagged

Just post it here in the AVA circle, no need for the typical ACC (AudioCircle correctness, or should I say condescension).

You can always pm me, too.
