[Yaesu] FT-757 problem

it IS a light bulb. Yaesu used those to protect the front end from
extremely strong signals. If it goes out, you'll see degraded receive
capability. As far as I remember, it is a 6V 50mA bulb.

hi guys
I have a FT-757 with very low receive volume, only hear very loud
stations even local am radio stations only the very strong signals. so i
took the covers off and started probing around. when my finger got close
to part # L-03 the volume increased very much. it looks like a light
bulb, never seen any thing like it, its not a resistor or transistor or
capacitor. again it looks like a small light bulb. this is on the very
start of the receive circuit just ahead of the antenna connection

any ideas what i am looking at and what may be the problem with this
rig. I am just starting out trying to teach my self how to fix or
destroy radios

thanks guy and happy holidays
