Well, I it what it is. I am not DIY-Moron and I do not do undertake audio projects only for a sake of abstract audio experiments to prove irrelevant and nonrepresentational ideas.  There were no methodological of systematic needs in this project. Sine I clearly see the difference between the amorphous core and M6 core in context of Landhale transformers the idea was to find somebody who would do a dedicated HF transformer.  Also, during the same time the idea of use a single stage was brewing and the reasonable question was: way to use two transformers? The objectives were to illuminate dynamic limitation of ribbon in comparing to compression drivers and to see if it possible to rise power and transient without rising volume (very loaded statement)

So, when I approached different manufactures I was asking amorphous transformer between a ribbon and 3500 Ohm – 3 people offered me different design. I knew exactly what is necessary to accomplish I have absolutely no idea HOW.  The RALL’s Alex, also proposed to render the projects and he suggested that he has very clear vision HOW to do it properly.  He coursed the amorphous cores, did all circulation and built a less successful prototype and then the more successful final version of the transformers. I feel that considering that since he specializes on ribbon transformers generally I feel that he has more credentials to do this project successful then many other competitors… I very pleased with result; even though the transformer has a relatively high insertion lost.

So, this new 175:1 transformer could be used with a regular Milq and might be used only in context of a single-stage amp with a high-pass (the requirement for transformer was to roll of at 4K-5K) with objective to use the “Water Drop” above 13K, second order. So, it all came together as one unified solution.

The air cap? There was not better rechargeable practical cap, I made this experiment many time in many applications. In fact I will be trying in a week or so vacuum caps in there…

What is extremely differently-positive? The sound from the tweeter. I will comment on the Sound differences sometimes later when I feel comfortable to do it.
