hello everyone,
i have brand new onetics level 1 and level 2 output transformer for 2a3, 300b, and 45.
i have 1 pair of each kind of tube for level 1 and level 2.
pm me for details

Hello folks,
Thank you all very much for inquiring about the transformers:
Here are the specs for the 45, 2a3 and 300b along with their prices.
45 opt- level 1 is $360.00 for the pair
45 opt- level 2 is $760.00 for the pair
2a3 opt- level 1 is $300.00 for the pair
2a3 opt- level 2 is $700.00 for the pair
300b opt-level 1is $300.00 for the pair
300b opt-level 2 is $700.00 for the pair
O-Netics Audio Output Transformers
All transformers are power transformers, but not all power transformers are also audio transformers, that can pass signals above 400 Hz with any hope of fidelity to the original signal, even though they are excellent power transformers. While most transformer designers understand this quite clearly, very few designers are able to alter the subtle internal activities within a transformer, with the specific intention to change it from a power transformer to an audio transformer. O-Netics has this capability, we have spent the time and money on R&D to advance our understanding of the most subtle relationships within a transformer. The results are found in our audio transformers, with exceptional information retention, an extrodinary lack of energy storage or phase shift, at frequency extremes.
Our level one audio outputs will outperform all of the famed "golden age" of audio outputs. Level two outputs add even finer detail to the already astonishing amount of information found in level one devices, due to a core material change. Level three goes all out, with 16 interleaved sectors in place of 10, even thinner high performance dielectric barrier material and extremly small diameter wire strands, woven into Litz type 2 cabling, for all secondary windings. In addition to this the core material is also changed.
We do not use silver or impossible to maintain oxygen free copper winding wire, nickle or amorphous core material, or any of the other popular material driven aids. Instead we utilize commercial materials in subtly different designs with very specific motifs that come from our unique R&D program. Our designs rival and typically exceed the finest devices provided by our esteemed competitors, in information depth, accuracy of placement in a perceived sound field and increased levels of tone and transient color and internal gradient structure.
Our outputs are designed for extremly long life. Typical mean time between failure is expected to be 100 thousand hours. In addition the transformers will meet CE 6500 safey standards for non power grid connected transformers with a high voltage to safety low voltage transformation. All of the materials utilized in the coil structure are UL, CSA and CE6500 rated for continuous operation at 130 deg C, with electrical safety barriers rated for continuous duty at 200 deg C.
thank you

When I talked to Onetics they said there were 2 different core sizes they use. Are these OPTs built around the larger or smaller size cores?
i think that they are indeed OPT's.....
Bud Purvine is the man...he is my mentor when it comes to OPT making....😉

hello Redboy,
here is Buds answer to your inquiry,
The 45 tube requires considerably more primary inductance than does a 300B or 2A3 tube, 38 Henry vs 18 Henry, at just off of zero AC signal, with full DC current flowing. This requires 43% more turns, within the same volume. Those extra turns mean smaller wire sizes and that in turn requires slower winding speeds, to force the wire to lay flat and smooth for every layer. So, a combination of more expensive copper and notably more production time, by our most skilled and highly paid employees. These coils are of such complexity that none of the winding can be done by automated machinery. They require a skilled hand to guide the wire, while controlling rotation speed. So, an expensive employee is involved in every turn of the winding arbor.
Thank you
Thanks turbo these baby sounded amazing big upgrade from my Sophia opt on my korneff 45. I wish I have more money I would totally get the level 2. Anyway thanks for the smooth transaction.
great opt
great opt
Hello Merlin,
I will have to check with the post office and will let you know. I recently shipped a 25lb package to Ukraine and paid $60.00.
I will let you know by tomorrow. Thank you for the inquiry.
