[ARC5] VT-4-C

[AirRadio]

VT-4-C, well I am still in a daze after seeing these go through, 
250360269284, glad I have a few stashed away, trouble is they are often soft 
nowadays, only buy ones with a big silver getter, not ones with a brown dot 
or any signs of whitening.
Apparently the VT-62 (801) is a good substitute for the VT-25 (10) in the 
BC-375 and BC-191.
My BC-375 tends to FM a bit and yet the BC-191 never seems to and always 
gives good audio, most odd as they are both original and running dynos.
