cr Hallo, I'm "burning out" half of the final transistors. Can someone
cr tell me what am I doing wrong? Should I verify something? I checked
cr already all the components on the board and everything looks OK, but
cr after 5-6 minutes the transistors show a B-E short, and nothing works
cr anymore.Thank's for your time. Best regards. Criss

This is an audio amplifier right? Put 100 ohm power resistors (or a
lamp) in series with the collectors to limit the current until you can
determine which voltages are wrong. It may be an idle current or a DC
balance problem. Don't connect speakers until you are sure it is fixed.

.... Is reactance then illusory? No, it just appears that way...
