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,

Andrew Kopke
