[Yaesu] lamp fuse replacement in ft-102

[Kz2i at aol.com]

the receiver in my ft-102 has mysteriously gone quiet.  only  hear signals 
that show as 20 over s9 on other rig.  i suspect that it is  the lamp fuse under 
the finals.  my question is: 
has anyone SUCCESSFULLY replaced that bulb with another  type such as screw 
in or bayonet type?    putting a socket in a  more convenient place?  would it 
have an effect on the gain in the receiver  (i have a feeling it will).  i 
have ordered replacement from yaesu, but  thought i would investigate other 
avenues.
 
i believe this bulb (grain of wheat type) is used in other yaesu  rigs.  as a 
side note, the order taker told me it is a discontinued item  and they have a 
few hundred left before stock is gone (i ordered 10 just to have  on hand).
 
any help guys?
