Hi.The poster said his 813 can trigger big fires on delivering 25-30W O/P. Hence my question: how?
Assuming yr guess is correct, so "HOW" can Vp=850V trigger big fires when handled properly ????
Let me give you a hint to save you keep on guessing, what will cause fire? A commmon cause is HV shorting due to bad insulation handing. So, stop going off-topic (it stinks !!!!). Answer my question for the poster!
Yes, a 813 SE can deliver 380W with Vp=2,250V operating at class C.
But this is NOT my point. My point is at such high O/P power & dangerously high Vp, slighly mishandling can cause fireworks. So "how" can a 813 operating at your assumed 850V delivering 25-30W can trigger big fires. This is my question. Please answer it.813 is a transmitting tube which can handle up to 120MHz, is there any technical reason why it can't handle a class D switching speed of typically 500KHz for audio application?
Yes, 813 was designed over half a century, but what would stop it using in class D todate? I want to know.
