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

[scott sheppard]

I have recently recieved my new to me Argosy. In one of the many mods I note it suggests replacing a 33uF elec cap with a 22uF Tantalum cap. This is to help reduce the AGC pumping action. For fun I replaced the cap with a regular 22uF cap which had no real effect. Would a tantalum make that much difference? Has anyone done this?

cheers
