Tip & How-To about Audio Players & Recorders
TIP: when checking transistors, if the transistor appears shorted in circuit, you need to test it outside the circuit. This is because they are sometimes across a coil and will therefore appear shorted while in the circuit, even though they aren't shorted at all.
To remove them from the circuit I find it's easiest to simply clip 2 of the 3 leads, test, and solder the lead back together if it's ok. If it's bad, I clip the third lead, and then desolder each leg individually...much less effort and time that way!
