I connected my amp to an old speaker with a somehow faulty crossover, it did the following:
Played back sound “normally” for like 1 second, skip, maybe 0.5 secs, skip, maybe 0.25 secs, went blank. Doesn’t turn on. Can’t measure it since it’s can’t be turned on.
An audio repair boutique thinks the hard skipping behaviour before breakdown indicates it’s most likely the output transistors that blew. Is this quite clearly the case?
The fuse would’ve blown instantly… It does make sense the output stage would skip like that before deciding “alright that’s it”. Since the relay doesn’t click on when pushing the power button, is this the power supply being in safe-mode now so to speak?
Might this have been an issue with the current somehow being oscillated or the crossover presenting an overly reactive situation?
Why might a sturdy Electrocompaniet that handles under half an ohm break down like this?
(Well, it’s actually GREAT it broke, since now the power supply electrolytics will get replaced in the repair, the toroids shielded and KLEI RCAs and terminals added as a nice upgrade! Should I bother with having the gauge of the wiring to the toroids increased for less impedance? Probably superfluous?)
