This is in an AM/FM radio in the tuner circuit it has on it Sony A376 and below that n5, has 4 legs on it and no markings on the circuit board. I have tried cross reference with no luck, also tried the Sony web page. It looks like a transistor but has 4 legs on it

its likely to be a 2SA376
all the info I could find is ....
2SA376
FVG
Various
pnp transistors,transistors
FVG, 2SA376, Ge, PNP, 60mW, 22V, 10mA, 85>C, 50MHz, 0.4, 48T, SOY, TO72-2
2SA376
Germanium PNP
N/A
pnp transistors,transistors
Category: Germanium Transistor, PNP Transistor, Transistor
MHz: <1 MHz
Amps: 0.01A
Volts: 22V
there were no pdf datasheets
for you future reference most japanese transistors drop the first 2 characters on their devices
B500 = 2SB500; D380 = 2SD380 etc etc
2SAxxxx and 2SBxxxx are PNP transistors
2SCxxxx and 2SDxxxx are NPN transistors
2SKxxxx, 3SKxxxx are FETS either single or dual channel
