George,
Everyone reading this thread can see that I and atmasphere talk in very specific terms and in detail when we talk about EPDR. You are not fooling anyone but perhaps yourself.
Since you are such an expert on EPDR, tell everyone, specifically, what was inaccurate about atmasphere's post about tube amplifiers and EPDR. Here, I am reposting the relevant section:

Tubes are a bit different from transistors in a number of ways as we all know :) One of the ways they are different is the Safe Operating Area (SOA). With tubes you can exceed the SOA without damage to the tube if the tube is allowed to cool off afterwards. A tube dramatically overtaxed, such as in a loss of bias, can turn cherry red from heat, but if allowed to cool off, and the problem corrected, can continue to give normal service.
