Subject: [Amps] No grid current meter on FL-2100B?

I'm trying to help a friend (in another state) convert his Yaesu FL-2100B
from 572Bs to GI7-BTs. I just noticed that there is no grid current meter!

Is there an easy way to convert the SWR meter to monitor grid current? A
Google search turned up nothing about adding grid current monitoring to the
FL-2100*.

TIA.

73, Mike

##  I had a 2100B back in the 70s.  Myself and several other 2100B owners noticed the 
swr meter was  semi useless.   The indicated swr rose as the po increased.   I once heard
an old geezer remark to his buddy that he never ran it more than 400w pep out, since at 600w
pep out, the swr increased too much !   Re-using the swr position as a grid meter would be a 
superb idea...and use an external, real swr meter outboard.  Is there an online 2100B schematic
available ?   This may well be doable.
