Dynaco kit amplifiers
This privacy statement describes how PassDIY collects and uses the personal information you provide on our Web site: passdiy. It also describes the choices available…. After 22 years, it appears that quite a few DIY enthusiasts are still eyeing the A40 Class A amplifier design, but are discovering that not a single transistor from this design is still available. Lambda appears to still be in business, but not in the business of power transistors. Common everyday complementary power darlington transistors will substitute for these.

Dynaco ST-70: A Timeless Classic
BTW, I had a blast putting the kit together! GT customers report great results with bi-amped Martin Logan speakers, Magneplanars, and all kinds of speakers that cost many times the price of a GT We expect similar results with the GT The PR preamp has also been favorably received by many audiophiles with very expensive systems.
It's fun, relaxing, and educational. Completing a kit provides you with a great feeling of accomplishment, and Akitika makes complete kits that make it easy to build great sound. When you add your labor, you get high-end sound for a bargain price.
The kits contain everything you need to build great looking, great sounding equipment. We make great sounding, proven designs backed by knowledgeable support. It was a great project for me to get the rust off, as I had previously built a few Dynaco kits way back in the s, but nothing since! Frankly, I wondered if I could still do it! So, I was a little reluctant. Now, I did not undertake this project lightly, as I knew it was bound to be more difficult, what with the number of boards, steps, etc.
I decided to purchase the whole package, and in addition to the preamp kit, I opted for gold phono connectors, powered potentiometers for balance and volume, the headphone amplifier, and the phono preamplifier.
Therefore, as opposed to the three boards necessary to complete the amplifier, I now had six boards to stuff and wire together! Personally, I have found that circuit board holders along with a 3. Also, I use a 16X magnifying glass so I can read the numbers on the very small capacitors, operational amplifiers, etc. In one case, I had inadvertently soldered across a trace, thereby nullifying the circuit.
In another, I mixed up two of the op amps on the phono board. I might add that I had several questions along the way, and Dan was very prompt in his response to me, each and every time I emailed him. In one case, he was concerned enough that he called me on a weekend! I challenge anyone to show me any head of a company who is as concerned with customer satisfaction! In addition, the parts and circuit boards themselves, down to the case and screws, are absolutely first-rate.
Now for the good part, how the preamp sounds. Understand, I was comparing it to an old Dynaco PAT-5 solid state preamplifier, but one that had been completely restored. Stereo separation is better, signal-to-noise is amazing, clarity of highs and lows are much improved, tone controls are just superb although you can switch them out of the circuit if desired , there is virtually no distortion, the remote control is great, and I would bet that it would hold its own very easily with preamplifiers in the four-figure range!
So, once again, Akitika, in my mind at least, has proven to be the best-designed solid state equipment on the market, both in regard to easy of assembly, superior parts, and the best instructional manual in the business. My next project? I am going to update some of my old Dynaco equipment, using you guessed it! Those are certainly great kits, but you need an old Dynaco to get the ball rolling. What if you want to build a new kit, from the ground up? That's what you'll find at this web site.
Lots of people used to build electronic kits. Heathkit, Eico, and Dynaco let anyone assemble great stuff and save a lot of money. On top of that, building the kits was relaxing, educational, and rewarding. Akitika has designed high performance audio kits. With our great designs, the carefully selected parts, and your labor, you get great sound and a great value. Critical signal path capacitors have high linearity NPO or poly-film dielectrics.
Metal film resistors, a toroidal transformer, and an elegant basic black custom chassis are the great ingredients that produce remarkable results. The kit uses all through-hole components. The circuit boards have been specially designed with generous spacing between all the soldered points, making assembly easy.

Not all vintage buys are wins. None of that diminishes the excitement I get from the equipment that has taken up permanent residence in my systems at home, but reality bites sometimes. Two companies that have recently struck my interest are Dynaco and Heathkit ; specifically their homebuilt kits which to some degree you can still buy. DIY amps, receivers, and audio scopes that were not uncommon the the s and s.

Modifications To Dynaco Amplifier
Founded by David Hafler and Ed Laurent in Philadelphia, Pennsylvania in , Dynaco was an American hi-fi audio system manufacturer popular in the s and s for its wide range of affordable, yet high quality audio components.. They also manufactured other tube and solid state amplifiers, preamplifiers, radio tuners and bookshelf loudspeakers. Dynaco was liquidated in , and the trademark is now owned by Radial Engineering Ltd. In David Hafler and Herb Keroes started a Philadelphia-based company called Acrosound to build and sell audio-quality output transformers, primarily for home electronics hobbyists.

Dynaco Stereo 70 Amplifiers
Two independent power amplifiers provide 35 watts output on each channel from a single, rugged power supply; may be combined for 70 watts monophonic. Patented circuitry assembled on printed-circuit board. Power supply is low impedance, choke filtered type. Power Output: 35 watts continuous; 80 watts peak, each channel. Hum and Noise: Inaudible; 90 db below 35 watts. Output Impedances: 4, 8, and 16 ohms. Damping Factor:
Dynaco Amplifiers
Single-Ended Amplifier Input Stage Kit shown configured for capacitor coupling with input grid choke. We have developed a single-ended SE input stage with relatively high gain, making it possible to build a two stage amplifier with adequate input sensitivity to work in a wide range of audio systems, not just systems that use high sensitivity speakers. There are two coupling options built into this kit.
Antique Radio Forums
Founded by hi-fi pioneer David Hafler and Ed Laurent in , a small company by the name of Dynaco unknowingly would become the most popular tube amplifier company of all time. Five years prior in , David Hafler and his friend Herb Keroes started up the company Acrosound, dedicated to building audio quality output transformers. The Acrosound transformer circuit quickly became a staple in the early s for electronic hobbyists building their own amplifiers. Following the success of their transformers, David Hafler began selling entire amplifiers as build-it-yourself kits—a rather novel idea for the time.
Dynaco and Heathkit: The Budget Audiophiler
When you enjoy listening to music or using ham radios, you may need to pair the radio, transceiver, or stereo receiver with an amplifier. Well-built amplifiers and replacement parts allow you to hear the full range of the audio at a greater distance away from the equipment that is outputting the sound. On eBay, you can choose from a range of affordable Dynaco amplifiers and replacement tubes. The available types of vintage Dynaco amplifiers on eBay include integrated amplifiers and power amplifiers. The integrated amplifiers feature a power supply, amplifier, tuner, source switching, and volume control in the same housing. Power amplifiers accept the signal, amplify it, and output it. An integrated amplifier has a dual function as a radio receiver.
Just pick the upgrade kits that you want:. You can bring your Dynaco Stereo Power Amplifier back to life. Even if it's working, you can make it sound better than it ever sounded.
Sorry, but could you please give a little more information.
I apologize, but in my opinion you are wrong. Write to me in PM, we will handle it.
Well done, the brilliant idea and is timely
Just what?
You have hit the mark. I think, what is it excellent thought.
