One of these socket testers is great and one has been over-engineered with lots of extra weaknesses as a result. In hindsight I'm wondering if the hot resistors (110C) were masking the transistor or if the transistor itself was getting that hot. If it is dissipating about quarter of a watt then it should be within its capability.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of KZitem's advertising algorithms allowing it to be a bit more dangerous and naughty.
