What is this part?

[johnecashflo]

This part came out of the linear plate on the bottom of a 4300-300. I replaced all the pills and with both fuses in it would keep kicking my breaker on my power supply. With only the number one fuse I could get half the board to work. Removed this piece from the board near fuse number two and now I have full power (over 300 watts). And it seems to receive ok. I was just wondering if anyone can tell me what this is. I would like to replace it or does anyone know if I can run the radio without it with no harm to the board. Cb tricks has a schematic but no part numbers. Thanks for any help you can give a novice

Have a DVM?
Test it . . .

Looks like a SMD transistor.

Take another picture but not so close. It looks kind of like a mica capacitor but it is too close to tell.
