[ARC5] ARC-5 T-20 Frequency coverage and other questions

[Andrew Kopke]

 Hello all, I'm new to the group and a
 new owner of a ARC-5 T-20
 
 After doing some reading on line ,It appears as though this
 model could cover the 80 meter band mentioned in one of the
 conversion manuals ( I think it was "Command Sets" published
 by CQ ) Anyway, That mod mentions adding a capacitor
 somewhere . There is another modification that involves C-60
 and, making the plates of that capacitor fully meshed. I
 took the cover off and sure enough the paint seals were
 broken and the capacitor was closed.
 
 I haven't even begun building the power supply as of yet . I
 do have  a 24v dc 2.5 amp supply.
 I have alot of questions to follow ,but my first question is
 :does anyone know if this transmitter will cover the bottom
 CW portion of the 80 meter band with the plates of C-60
 closed?  I don't see any other modifications done. I
 washed the set in the sink with dawn and rinsed with
 distilled water  unfortuately, I washed off the white
 ink behind the plastic window of the roller inductor scale
 ,but can still see the number scale engraved in the plastic.
 I suppose I could just get a white paint marker and re- do
 it . Any thoughts? 
 
 Thanks for any insight,
