Canadian company has acquired the "Dynaco" trade name ?

1) VTA ST70 $1235 + shipping WIRED with ALL tubes & EL34 output tubes.

2) VTA ST-120 WIRED and TESTED amp with a complete tube set with Sovtek 6550 output tubes > $1600 + shipping.

3) WIRED PAIR OF M-125 amps with ALL TUBES $2895 + shipping

The proverbial no-brainer!

Need I point out that for that price, you could get a pair of M125 monoblocks, wired, and have about FOUR times the power?

give me $1500 and I'll build you a new VTA70 with integrated preamp, fully remote control, and auto-bias on all the tubes, and even that bright yellow paint !!!
Seriously, no joke . . .

meh!...an overpriced and underperforming (for its price) regurgitated ST70, trying to sell itself on the Dynaco name. Not to mention some of the negative points by Bob!
Seriously.....$3000.00 ???????

Rather too steep for me to buy.... But give them credit they have on the whole produced a good looking amplifier. I agree regarding the width and Bob's comments. Maybe the extra width was to allow for the cooling slots given the PCB construction.

After all there was a leader in a certain country that said size does matter fairly recently.

In the other post the yellow chassis is not for me. Who wants a custard coloured amplifier??

Perhaps with some green added to balance it out ? =]

Are the triode pairs in a single 12AU7's not closely matched enough for the task of accurate phase inversion in their mind and  is this why they are using two - or is there another benefit I am missing?

Any random choosen ecc82/12au7 ( or any tube) is unequal to any other. That is why
"old timers" designed amps to compensate for tube performance. Feedback is one of the
big helpers here, today CCS is another. Or just plain intelligent design. A concertina
is inherently balanced, a paraphase or LTP is not. If an unbalanced design is choosen
then adjustment pots must be designed, and so a manual procedure for trimming.

Have a look at MkIII ( or ST70) if you like, designers know their trade.

The alternative is to demand matching of tubes.

Anyone actually bought one of these things yet? I was looking for a google pic of the bottom of the chassis to see if that was open enough to allow all those cute extra slots on the top to actually work. Nada. Zilch. If they're looking for a chimney effect to cool the components, cool air has got to come from somewhere, eh.

PS - I was all ready to sue if the new production units looked anything like mine ... ;-}

Thnx Peterh and W. That got me to reading about some interesting things.
I see one dutch reseller of tubes having  balanced versions of the 12au7 on sale for a few € more.


Well   if nothing élse breaks this month, the next might see 45 pounds of puzzle heading our way =]

But to not let this thread stray too much lol - yes, this st70 reboot has some interesting sides to it but   being most of the way to a decent mc275 mk VI in price, and over some other offerings like those from Cayin with more power and more features - I wish them the best but   it just does not scream  buy me  at me.. The presentation also to me looks more at home in a studio than in a livingroom.

You don't need matched ecc82 in the vta70/120 amp, it uses CCA and feeedback. Working tubes
within spec is what you need.

Oh yes I found that out when you remarked on those things in your previous comment I did some searching and found a nice page on the mkIII and others by someone who explained the circuits nicely.
There are quite a few people out there hosting some very interesting ( and way out of my depth ) books on the subject I found -   The Morgan Jones one is on my reader now ( page 396 and onward on this subject ) though am still looking for the Audio Cyclopedia book - seems to go for prices approaching a set of nos 12au7's from some British WWII airfield on Amazon =S

I can't comment about the sonics of the Radial / Dynaco amp, but I do know Radial Engineering as a company quite well. They are far from a fly-by-night operation, having being in ;business for something like 50 years. Their history is in Pro Audio and their products are highly respected in that field; some of their units are considered "must have" in the Pro recording, live performance and installation spaces.

They have been the Mogami distributor in Canada long before that line of cable was "discovered" by the audiophile crowd. They were the largest customer of Jensen Transformer (California) and when that company announced they would cease operation, they purchased the firm in a friendly transaction and injected (needed) cash into the operation, which as a result continues to manufacture that well respected transformer (line, 600ohm, moving coil cartridge, etc) line.

I very much doubt they would not have secured the necessary rights from the legal trademark and IP owner to resurrect the Dynaco brand, and I expect any legal challenges will be dealt with appropriately over time. I am not suggesting they are intending to resurrect the original Dynaco products and service, just that they are likely to offer a quality product should one come into the market. I do know they have also purchased the rights to the Haffler trade name from the OP owner and that the new products under that brand are real and can be purchased from resellers.

They are not a "high end audio" company; these lines are a new area of interest for them and I would expect it will take some time for them to develop a dealer network and to navigate the unique aspects of marketing in comparison to the music industry.

None the less they are likely to have performed due diligence and are in my opinion serious about entering this area of audio and I expect them to show appropriate respect for the history of the company. I don not expect their resurrection of the Dynaco trade name to affect the existing classic Dynaco businesses negatively; it may even be a benefit by putting the brand into the public eye to a greater extent than in the recent past.

In particular I think there will be a clear line of separation between any new Dynaco product and the classic components this site is concerned with. I don't see them as usurpers or someone who will cheapen the brand by milking the goodwill (unlike, say, the current owners of names like Bell & Howell, etc). I know these developments seem alarming to lovers of classic Dynaco products, but in my opinion I see no need for panic. As to the new amplifier they have announced, it is not really selling into the same market as the one this site's members are concerned with. Also I think it is worth mentioning that Radial manufactures all of it's products in North America (Vancouver BC or California).

Oh, and yes, this is my first post. But I didn't join to comment on this topic, I came across it while perusing the site as a new member.

In what capacity?  Customer?  Business associate?  Something else?

Just curious...

Customer (wholesale Mogami, retail Radial product owner), experience (Pro Audio production, recording, installation, guitar player). Their Direct Boxes are a studio/stage standard. Virtually everyone who plays guitar, keyboards; people like Eric Clapton to Metallica use their stuff. Reputation is based on ruggedness, reliability, and sonics. The curious can seek out reviews in the Pro Audio press (Guitar Player, Sound on Sound magazines, etc). Virtually the only complaint people have is they cost more than the Chinese built competition (Behringer, etc). If you are a Professional in that area, and you want the best, it's what you buy.

Put another way, they're the kind of company you would want to buy the brand, I'd take them even over someone like Harmon International, aside from possibly Harmon's ability to throw unlimited money at a project. Customer Service is solid and responsive. Before Marshall bought equity in Mogami they were the sole North American distributor. You literally cannot buy a CD or album or watch a TV production (all the networks, NFL Films, etc) that doesn't use Mogami cable somewhere in the chain.

With regard to price, all I would say is members of this forum are well aware of their options, choice is a good thing, and if Dynaco were selling in 2017 dollars with a full retail distribution chain (where a BoM would be about 20% of retail), it would be more than $3K for a new ST-70.

Fact still is, however, that Bob’s, Kevin’s and Frank’s Stereo 70s are about, what, half the price or less. I am skeptical that the Radial Stereo 70 would sound so much better as to justify the higher price, if it sounds "better" at all (again, I’m skeptical).

Perhaps the new Radial Stereo 70 would appeal more to a non-DIY, "boutique" crowd who might neither be aware of nor understand the other choices. In any case, if people want to spend $3,000 on it, it’s their decision. For me, I can spend some money on this stuff, but I’m not Jed Clampett or Thurston Howell. I’d rather pocket the savings and use it on something else.

Yes, and I don't think it's necessary to remind members of this forum one more time what options there are for original ST-70 and other Dynaco product.

It's an Apples-to-Oranges comparison in any case; the Radial product is a fully assembled retail packaged retail dealer network market amplifier. I fail to see any likelihood of direct competition.

Finally, although it's extremely common, I never understand why people complain about prices for products they have no intention of buying. It is both preaching to the converted, which is always pointless and never changes outcomes, and speaking to an audience that doesn't exist, as those who would consider such a purchase aren't among those such comments are likely to reach. I do understand the sentiment, but the effort is wasted.

The heritage of the company behind this Dynaco reboot does clarify the styling to me - it definately looks like studio not livingroom gear. My google bubble has been inserting adds for this thing into some sites this past week ^^ They should get some of these things out to some reviewers asap though eh..
