So I have some bad news - I've decided I cannot build and sell amplifiers publicly on Head-Fi.
I know this might come as a shock considering I only just recently announced the Airmid OTL and had discussed plans for future headphone amplifiers, but after thinking it over and discussing it with my partner, it just isn't going to work for a few different reasons.
First off, I am a critical care healthcare provider and my profession is pretty demanding. Given the current state of affairs in the critical care world and recent develops in my professional life, I don't have the time and energy to essentially work two jobs, which is what building amplifiers feels like it will become. Also, there is a certain degree of legal liability when selling high voltage audio equipment and to fully protect myself would require a commitment to small business ownership that I am not willing to make. I wanted to keep building amps "casual", but when there is 200V+ inside the chassis and the possibility of electrocution, it cannot be done casually without taking on some degree of risk. And without going into great detail, doing it would make me unhappy, ultimately.
So I will withdraw the Airmid OTL from Head-Fi. I will finish the orders that have been placed and provide future service and support for those amplifiers, but I will not be taking any new orders. I'm sorry to have led anyone on, I hesitated in the past at the idea of selling amplifiers, but thought I should try it out and see if it was going to work - I now know without question that it won't. I'll continue this thread if people are still interested in learning about tube audio design and potentially working on their own projects, but I won't be offering anything I show here for sale.
