The Dynaco Tube amp series are legends. Now there are an abundance of kits and accessories to resurrect those old tube amps to astonishing levels of performance. But beware for anyone trying to do upgrades there are more dangerous voltages present than in modern transistor and later amps so take precautions.
I'm a lifelong guitar player as well as audiophile. Guitar amplifiers are one of the very few devices nowadays that are all tube. Believe me, a 30-35 watt tube amp will peel paint off the wall when you crank 'em. No one ever said those old Vox AC30's lacked volume 🤣
This is a steal , the quality and sound could not be beat in tbe price , I know guys that bought chifi tube amps 2 and 3 times the money and ended up very disappointed. I tried to warn them but there asian persuasion got the best of them , like one friend that married asian and it cost him dearly .
I'm not surprised. 60 years ago, Roy Allison used this amplifier in the form it was originally in to conduct live versus recorded demonstration at trade shows. I was fortunate enough to attend two of them. The first was a solo guitar. The guitarist was flanked by a pair of AR3s. The second was a 1905 Nickelodeon flanked by a pair of AR3s and AR4xs. I'd had a lot of experience with AR3s, and frankly I didn't like them. They seemed to have a muted muffled treble. But the demos were remarkably close and it wasn't until a few years ago that I found out how he did it. First, the settings for the midrange and tweeter controls were not flattest at the dot indication but at max. This was because Edgar Villchur who was the inventor of the Acoustic suspension woofer and the dome midrange and tweeter felt records of the day were too bright. The other was that Allison set the treble control on his Dynaco PAS3X preamplifier he used to boost. The overall sounds between live and recorded were remarkably similar, the best demo of its type I know of. So now I understood. As an electrical engineer I know that a series inductance is a low pass filter. It will attenuate high frequencies. There are other and IMO better ways to adjust the overall frequency response of a sound system but in this day where "less is more" that is not the prevailing philosophy of audiophiles. BTW, in the mid 1950s members of the NY Audio Society, predecessor to AES took 4 AR speakers and 4 Western Electric 150 Watt amplifiers to Riverside Church in upper Manhattan for a playoff against an Aeolian Skinner pipe organ. The results established the AR 12" woofer as the reference standard for low distortion extended bass response and was even used in medical schools to teach students heart sounds. As an engineer it took me nearly 25 years between the time I had the analytic tools and the time I figured out how and why it worked and is in my opinion the best design. (Not all sealed enclosures are acoustic suspension and even Villchur didn't fully understand why it worked.) The analysis combines two well known principles in physics, Newton's second law of motion applied to forced oscillation and the ideal gas laws. The secret is that the mechanical damping factor is controlled by forcing the speaker to push and pull air between the fibers that fill the cabinet. The damping factor is directly proportional to the velocity of the air. The aggregate surface area of the fibers is enormous and the frictional loss between the air and fibers is turned to a tiny amount of heat. This is the same principle that explains why the space shuttle gets hot reentering the earth's atmosphere at high speed. Newton's second law applied to forced oscillation is used in many applications such as the design of the suspension of your car. Three factors tune the FR, moving mass, damping factor, and spring constant. So despite its relatively low output and AR3s outrageously low impedance at some frequencies (we blew up an HH Scott solid state amplifier with a pair) Dynaco Stereo 70 is a winning design and improving it makes it a good choice for vacuum tube amplifier lovers.
Danny, Your observations about tube output "it never ran out of juice" is something I have been hearing my entire life. The old "tube amps have more watts" or "these are tube watts" or other descriptive statements were all trying to say the same thing. It could be the iron or the two paired together; it is just there. The iron stores energy, there is no question about that one. I had a stint of over a decade working in commercial aircraft power systems design - the hardware end. But to design right, one must absolutely understand the parts of the circuit to design it for optimum performance. My approach is that in aircraft there is no room for mushiness; it is either there or it's not. My designs took a little longer, but they also worked very well. Faster is NEVER better. I know the role of magnetics thoroughly - I'm sure you do as well. Iron or the various core materials in the signal path unnecessarily is not without unforeseen consequences. It can either aid or mush up the signal. Keep it out unless it is needed. I love this video. Good stuff.
An audiophile friend with a couple dozen iconic amps and speakers has an upgraded ST-70… and it is hands down favorite tube amp. A pleasure to listen to. If you have the means… do it.
Before buying a tube amplifier, you need to measure it using the RMAA program. Using the Multitone test for the presence of a high-frequency SPECTRUM in the signal
@@j-rod6420That's the blessing of selective golden ears, can easily pick noise and distortion on a mains cable below the resolution of state of the art equipment, let alone hearing, but not the tube gear well within the either.
As a tube amp guitar player I can tell you that my 50 watt JCM800 easily keeps up with my 100 watt Boogie. I share the band with another guitarist and he has a few different 100 watt amps and my 50 watt keeps up. Tubes are just different beasts.
Great stuff! Glad you decided to devote some time to products like this. I've looked at a number of ST 70 versions, and I think the Miller version is the best.
The other room sounds quieter and clearer, this room needs no-res or Rockwool on the walls and maybe Ron's touch-on room treatment (which would be a nice video come to think of it, why don't you guys make a project of it)
Love tube amps! There's nothing like the sound they reproduce. Analog just has an essence you can't get from digital. I bought my daughter a nice Sony turntable because she loves music and plays multilpe instruments and now sings live on stage. She's only 17 and just finished her first year of college while making the deans list at Longwood University! She had never experienced anything but digital. Now, records show up in the mail all the time and that gift has become one of her favorite things of all time! Danny, keep em coming! Long time fan. Not many people who give it to you straight with no B.S. ❤❤
One actually could design a ”digital” amp to sound just like a tube amp. Its just a matter of adding the right kind of harmonic distortion. 🙂 But yeah theres something magic with those glowing tubes 👍
@@magnusdanielsson2749Indeed, ie., Carver's transfer function demos back in the 80's ... he could emulate a subjective tubelike subjective characteristic from a solid state amp.
@daviddrake6875 it was this- Sony PS-LX310BT it is highly rated and after some research I decided was best for my needs. It sounds wonderful on a set of nice monitors.
I tried my 85dB standmounts with my Dynaco ST70 and it was a little bit of an anticlimax. There was music, but to say 20% of the Dynaudio C1 potential I would estimate....
likely due to the fact most ST70s only have a single feedback circuit, meant for 16-ohm speakers, even though they only have taps for different impedances. So, without modification, most speakers are going to sound like they have a wet blanket thrown over them. The one in the video has custom feedback circuits you can switch between to fix that issue.
The real point to tube amps today is. There are a lot of designs that are nothing more than an embelished old circuit design. Even more importantly, you can not get valves that are as good as old production. I dont care what anyone tells you. They are just not made as well. And, yes, I do own tube equipment, a pair of Gray AM 50s, Dyna SCA 35 and a VTL Intergrator.
I am so happy i got to see this i am struglin to get someone who heard the original st70, vacuum tube audio version from bob latina, don sachs version, kenny russel from getdynaco version… I would love to hear your 2 cents on these amps
Time for John from Musical Concepts /Design , he makes some kick ass power amps known for amazing resolution . Also mods for Hafler amps . Some very very neat sounding amps and mods .
What would you think about using the Eversolo DMP-A8 as a preamp ? I only stream, so I am trying to use as few things in the stream as possible, also trying to get all the benefits and balance of using tubes. Speakers are Q Acoustic’s Concept 50.
The BIG problem in the old Dynaco is the quality of the electrical supply. From Miller web: * No Rectifier Tube Eliminates a weak point in the original ST-70 design, the single heavily loaded 5AR4/GZ34 Rectifier Tube. * Solid-State On-Board Rectifier Some Audiophiles claim to prefer a tube rectified sound that can “distort” or "sag" when under load (very desirable in a Guitar amp). With high fidelity sound reproduction the last thing you want is sag induced distortion from your amplifier’s power supply. NOTE: Most new tube amps designed today do not use a Rectifier tube.
Search on ST-70 test to find a video comparing an original ST-70 to one modified with a VTA board. FR, Harmonic Distortion, THD, and power output. Both measured similarly very good. Distortion numbers low, but higher than highly regarded SS amps with smaller numbers. Don't believe it is simply distortion that produces a tube sound, if that sound even really exists. Measurements are a good starting point to identify obvious problems, but do not define every aspect of performance. Switching between a highly regarded SS amp and a ST-70 rebuilt with a VTA board there are differences, not huge, but real. The SS amp has a claimed FR +0 -1.5dB from DC - 150,00K and distortion numbers in the second decimal place. We don't listen to numbers. We listen to everything in involved in reproducing music, including our room.
I always had ss amps and I found an old 1957 hardon kardon covered in dust at a old shop and convinced him to sell it. I spent a lot of time restoring and finally got no noise and I put on rush hemispheres and I started hearing things I never heard before and was like oh yeah I get it. But I was wondering if Danny has listened to any purfi class d or hypex and what he thinks. I'm looking for an affordable amp that hits most of the buttons and I am not sure if I should go tubes , class d or back to ab. Thanks
Danny, did some measurements on the video sound, suffice it to say you gotta add some bracing to the wall behind you and about 14 sheets of no-rez. That, and crossover your voice @ 120 hz with some sonicaps.
Great video, thanks, Danny! I would like to buy your tube connectors and plates for these if they are the right dimensions for my old Luxman amp! What dimensions are the holes in the chassis?
I have a pair of Keltiks too, I could never make them sing like I wanted them to. Made them passive with a pair of old Isobarik 8-ohm crossovers, not the same crossoverpoints between mid and base but I figured the woofers would not mind stretch themselfes a bit. I'm now using a 25watts Audolici tubeamp to drive these alleged very hard to drive Keltiks sing there heart out! I tell you - tubewatts ( from a well designed tubeamp ) is no joke!

The reverb, as long as there isn't any slap back, is better for listening to the human voice. The lighting is better to see everything clearly. There is however some clipping in the audio peaks of you speaking, which is most likely the gain being too high on the microphone's preamp at the time of the recording, or clipping being introduced in the audio from the compression applied in post production of the video. It is not the worst clipping I've heard. Cheapaudioman is probably the worst, at least in his opening music. Your level of clipping is not much actually.
