[TenTec] ARGOSY II as a 'new' QRP rig

[WO8L at aol.com]

Hi,
 
I'd love to have an Argosy repaired.  Anybody know how to into the  S-meter 
without destroying the radio.  The background discs displaying S  units, etc., 
had a tendency to warp and limit needle movement.
 
What are the replacement numbers on Argosy finals?
 
73s,
