Is C48 (component side, lower right) also missing? Can't really make it out on the photo.
The trace damage near the VGA connector should be checked with a multimeter. It looks quite severe.
1982 to 2001

Ah, I missed that. Thanks. It is in a different location on the CT6670 compared to board layout in the original post. It is a bit further down.

Yep, it is broken right off. sdz spotted it an provided the correct value for it (1nF 25V 0603). For the trace damage, would one just do a continuity test from the nearest point/pad to the correct pin on the VGA connector? I'm guessing I could solder jumper wires where required if something is severed.
My soldering skills are pretty basic so I ordered a practice board to get some surface mount practice 😀
EDIT: I cleaned up the trace damage area and did some continuity tests. The one trace that joins two pins on each VGA connector is defintely severed. I attached a high resolution image. You can see its pretty clearly cut. Might just use a bridge wire between the two pins on the back of the board.
EDIT2: The other scratched trace is also bad as confirmed with a multimeter. No wonder I had no video output (passthrough or 3D). Will need two bridge wires it seems.
Hi guys,
I'd like to know the value for c70 on a Diamond v2 8 MB.
Thread here: Voodoo 2, no image with Glide games
Thanks

Hi,
C70: 100nF 25V 0603
Thanks sdz!
Updated the beginning of the thread with component values for another Voodoo 2 reference design based board, specifically a Creative CT6670. This, with what I posted before, should cover most V2 cards out there.
tnx a bunch... i have a couple of dead / half dead voodoo 2...this will help for sure
