I am led to believe that this transistor came out of a (bass) woofer - one one speaker, and only one transistor (not two).
This is the best photo I can get:
The markings appear to read
L70M09CV MCCO - 0031
Googling L70M09CV comes up with nothing related.
Any idea what it is, a datasheet, and/or a suitable alternative?
I don't have a photo of the PCB, as it belongs to a Thai friend, who speaks no English, and my Thai isn't fluent, so more details are either sketchy or non-existant. I may be able to get a photo of the PCB tomorrow.
FWIW, I get 0.6V across the collector-base and emitter-base junctions, when forward biased - when checking it and assuming it is an NPN transistor.
