Steve, i have 470uf 16v and 10uf 16v. can the 470's be used in place of the 220's? if so all i would need is the wire and rca jacks.

EDIT:  NVM i found a set of 220's.

btw, was that yes to the ceramic cap between the composite and ground?

that is a hell of a find, nice work. However, it still should have the caps installed to protect the system from feedback. I dont think those caps would fit through the hole in the dust cover. Its the way he wants to route the wires thats holding this up. It does give me a crazy idea though. I wonder if tantalum caps could be soldered in-line with the wires. They would be small enough to fit through the dust cover hole, if you fed one wire at a time.

Just make sure the video cable (your yellow plug) is a 75ohm impedance cable/wire. Video cable/write is transmitting high frequencies and the frequencies will reflect back into the signal via the wire (this is why there's a 75ohm load at termination to match the transmission cable's impedance). If you don't, you can get ghosting/ringing and other artifacts.

I have never seen any artifacts or any other video issues when not using a capacitor. You should be fine without one.

its not video artifacts we are talking about. the caps are not to filter, they are to stop electrical feedback through the lines from damaging the system.

can't the caps be further up the wire from the connection point, and remain within the back cover?

by the way, I've been snooping around ebay for one of those tennokoe 2 banks.  currently nothing in the states, just some beat up ones in France. 

Hong Kong game doctor has one already modded for $30, not sure to trust them.
