Why do my caps resist?

I'm doing a composite-out mod, which seemed easy enough as the instructions commonly describe attaching to the leg of C45 and C44. Only on my board these are resistors, even though they still have silkscreening indicating capacitors.

 

It could go either way, it might have been found to create a better signal with resistors, or the manufacturer found they could save x pesos by changing the parts at the sacrifice of video quality.

Those are axial capacitors with color-code bands.

Heh.. Once I looked at an Apple //e motherboard and saw what I thought were bypass filter diodes across each IC. Upon close inspection I found a surface-mount cap in glass envelope, sized like a diode, looking like a diode!

No, just the basic mod with no additional components... the colors are a little dim but otherwise it looks nice enough.

Ah, ok

If you ever get tired of a little dim, check out:

If you just want to wire audio direct, this one is composite video only:
