[TenTec] Argosy AGC mods---tantalum capacitors--whats the difference?

[Stuart Rohre]

The tantalum cap specified might have a tighter value tolerance, which 
is important to setting the time constant of the AGC.  A regular 
electrolytic can be plus 80 per cent minus 20 per cent tolerance 
depending on the type and age.  The tantalum if of the military can type 
should be more precise at setting the TC.
