adding capacitors to my bpt cpc.

i have some caps leftover, i got sonicaps,audience auricap and jantzen silver z-caps . i was wondering where can i solder them and value to my bpt cpc center ,bpt says they can add V-Cap Teflon Capacitors - Teflon capacitor used in the filtering network, 125 per duplex, i was wondering who has done it themselves.
