There has been some elec cap replacement in this unit, so I thought maybe something's undampened/was assuming old high-ESR caps. But adding bleeding resistors here and there didn't really make a difference.
Both channels are doing this, though not with the exact same timing, so it's likely neither a faulty component (then it would be only one channel), nor something upstream (then it'd be more synced).
Plus, I don't know if this amp has always (i.e. before the recap) behaved this way.

Once the amp is out of protection, it will happily play for hours on end with no issue. _Sometimes,_ it will come out of protection normally, i.e. in 5-10s, as expected, though only one in maybe 20-50 powerups. What exactly makes the difference, I don't know. It does not seem to be thermal: even when warm, the amp will behave this way. Any hints and tips are appreciated :) If you want to dig deep, the service manual/schematic is available on Elektrotanya (or just ping me via DM) 3/3
