A Leap of Faith, sort of, thanks to Paul Yoo - The MISHO MYRONOV TUBE WOODENAMP and PREAMP!

Misho,

Thank you so much for joining. Welcome to the forum!
 
Paul and I absolutely love the sound of your preamp and amp on our Avantgarde speakers.

I know some have asked. You are making a phono preamp now? I’m sure that will be just as awesome as everything else.

I think you will need 10 posts before you can add photos but Paul and I can help if you need any additional help here on the forum.

Thank you again. I should be sleeping but I’m loving my music too much to turn it off.
 
Thanks a lot for your kind and inspiring words!

I'm making phono pre amp as well, it's a bit different - while having a separate PSU made in my "classic" wooden style, the riaa pre amp psrt had brass top and botom plates, in order to provide sufficient shielding. Using some wood inside as well. The topology is a bit different from used by most, I'm using passive split correction circuitry.
I'm adjusting the riaa curve precisely for each pre amp.
Tubes used - fantastic low noise ecc808, ecc82 and 6Н6П. Power supply has independent rails for different stages.
It's a phono pre amp that I'm also happy with. The only difficulties is that it requires too much time to make, assembly and adjust...
Still have no my own phono pre, the ladt I made went to a friend in Macao.... :)
 
Thank you for the additional information. I can imagine all the work that goes into each piece. I’m ecstatic with the end result.

Wow! That's quite a list of big names, between the two of you, to beat out!

Thank you Joe and Paul for a great words about my amps!

To answer some questions - each audio transformer used in my amps is designed and made by me. Each designed specifically for the task, and has been heavily prototyped, tested, auditioned and redesigned and again and again untill I was happy not with the sound OR measurements only, but both.

All my amps completely designed by me, the basic principles - simplicity, transformer coupled stages and transformer outputs.

The wooden chassis has a complex structure, each layer designed to accommodate corresponding parts, and after glueing together it become a "solid plywood" 3D unit :)

Warranty and service - I'm sure provide full service support for my amps, life long. But it will not be needed most likely - if amps used in a correct way and not abused - it will serve troubleless for decades. It was designed this way :)

Do not hesitate to ask questions, I will be happy to answer (if not going too deep where proprietary things are starting :)

And very important note - each amp is made by my own two hands, so production capability is very limited.
I'm trying to carefully plan my working schedule so there will be no dead ends in production.
I have no amps on a shelves (I wish but everything is gone immediately), so no sales as such but only making on orders.

Best regards,
Misho

Thank you! Just a few basic questions:

First, why did you choose the tubes you chose? Were you after a particular design or after a particular sound? Is it the tube or is it the design that drives the sound you want?
Second, why wood? Why not just go for a metal enclosure like everyone else?
Third, what inspired you to get into this? Was there a speaker you like that you wanted to sound better?

Good Luck to You!

In Paul’s case, absolutely! He and I were talking about it and he listens in disbelief. Especially since some of the gear costs many more times the Wooden gear.

Yes, some stuff like AirTight, Luxman, and Kondo has legendary name recognition. Most people would just settle and stop right there. Great to see you guys really go out there and find out for yourselves, instead of trusting the raves of others.

In terms of sound, where does the Wooden gear sit between the classical tube (more euphonic) tube sound vs. the more cleaner, modern tube sound?

The Wooden project has no tube sound. I know I know its hard to believe it and describe it. I would say they just play music ( hmmm this is just too common words ) They add nothing to the sound. Huge 3 dimensional sound. The separation is just unreal. Extraordinary sound. My Kondo has bit more fuller and warmer presentation so its bit different but I would ranking the Wooden project equal to Kondo.
 
I have to add that while I love sweet and euphoric SET sound, the Wooden combo is a little more neutral but still a little sweet on top - open, 3D, with detail sound but smooth. Like Paul says, just music. It’s a very natural sound.

Hi! Thanks for the questions.
I love the sound of this tubes. First it was ef12-el12 combo, but ef12 is practically unrealistic to find in a NOS condition and in a considerable quantity. So, ef86 as a driver was a good substitute, without loosing the tonal properties of the amp.
I'm experimenting with this tubes for two decades, and love it. There are few other faworite combinations of course.
And I do like triode connected penthodes.

Why such an amp in general? I was collecting tube amps for many years, searching for the best sound. Also speakers, and many other things. To get some basic idea about my project you xan visit my Audio Antiquary page at the famous social network and see. I was always lazy to make pictures, but you can see some of my projects and works - like WE or Klangfim. But I was never happy with the sound even of the best amps, even after complete rebuilding.
My amps always sounded better for me. I'm making tube amps for 39 years now btw.
Some how expirience turns in to understanding of my own way, and finally WoodenAmp project wss started. Of course it's much linger story.

Wooden? I love it. It started as an experiment, and turns out to be fantastic.

And speakers. My faworite still be Altecs, only two way - 604 or VOTT. I even had to invent my own crossover (waiting for patent now).
 
Misho,

Along with a patented crossover, are you coming out with a pair of speakers? You could tempt me with a pair as another high-ish efficiency design. Exciting times!!!

wonder how the 3.5wpc would be with my 97db speakers - unfortunately, probably not sensitive enough.

Hi folks, just joined the forum to be able to participate in this thread. First, as I was reading the thread to catch up, I saw this post and wanted to comment.

Please don't think 3.5 watts is not enough for "97db" speakers. A number of factors go into the interaction between an amp and a speaker. Going by that one single number will not give you the answer. For example the impedance curve of the speaker is important too. If it is fairly flat or does not have a big drop below 8ohms, that will make a big difference. The amp will drive the speaker to plenty of volume. 97 db from 1 watt is plenty loud.

Usually the dip below 8 ohms in most speakers is at the low frequencies. That is where power gets drawn. If your bass driver is light and fast and open baffle or mounted in a cabinet that allows it to move easily, the impedance curve should be fairly flat and the 3.5 watts will produce plenty of volume. Also if the crossover isn't one that absorbs power that matters too. Really the only way to know is to try it out.

At the moment I have the Wooden power amp connected to a pair of Proac Studio 100 speakers. These are rated at about 88 db and with the C3m version of the Wooden Preamp, I get as much volume as I need. No lack of loudness.

Also by the way, if it hasn't been mentioned, the Preamp can be delivered with the C3g tube. That is a much higher gain version of the C3m. The C3m is rated in triode connected mode at a "gain" of 19 (amplification factor). The C3g is rated (in triode connection) at a of 41. So just over double. When thinking about it, remember that more is not automatically better. It is system dependent. What is the output RMS voltage of your sources, and what voltage from the preamp will drive the power amp to obtain adequate listening levels without being too much. The most obvious difference from the C3g will be where your useful volume range will be on the preamp volume knob. Most higher gain preamps will show a fast increase in volume in the first half of the knobs turning range. The C3m will give a slower increase and wider range.

Hope that is helpful.

Thanks!

I have the full set of Wooden Amps. Very happy to have them. Using them one gets the feeling that every detail has been carefully thought out. The interactions of all the parts carefully optimized to work together in the best way possible. Fine tuned perfectly. Certainly there are other well designed and executed components out there, but many of the commercially produced ones just don't have the same sense of human touch and craft. That's a very intangible thing that might seem rather meaningless but it is a feeling these pieces convey to me anyway.

I think that it comes from the level of refinement. That is usually what anything produced by a highly skilled craftsman has over more production made products. It's the way by which you attain the highest quality. The passion that drove the designer builder to invest whatever time and effort was needed to satisfy the goal. That comes across with these.
 
Ned. Do you have an Riaa phono as well ? If so how you like them ?
