Per Atmasphere components. Posting in a public forum personal correspondence demonstrates Ralph's lack of integrity. Regardless, the time to be proactive was when I owned the gear, not now after the fact. I've previously addressed satisfactorily things Ralph presents in his 9/4 post and that his followers posted on 9/5 including what happened during the warranty period and why talking to him after the fact would not happen, though funny how things disappear.
Products as poorly made and as problematic as the Atmasphere amps and preamp I owned are solid reasons to mention them in a thread about your most disappointing purchase. Ralph insists I'm lying and have ulterior motives. I've endeavored but failed to understand what ulterior motives I might have, see my previous post, with the most logical being I was a sleeper agent for another company. I challenge someone to come up with ulterior motives that make more sense than the facts Ive described. On the other hand, Ralph has motive to sweep my experiences under the table.
Per the reversed diodes in the preamp. It is possible that was not the reason the 2 Caddock resistors severely overheated and their resultant color change. The reversed diode fault was what Ralph mentioned when the overheating resistors issue was in for repair at Atmasphere. As an aside making a global statement that no product can work if it has a diode reversed is an unusual theory.
