I just found this Voodoo1 with a missing cap (c101):

I need the cap values to replace. Also the leftmost cap dont have the values too.
On VGA legacy site has the same model but different revision (mine is Rev. G) There another V1 on same page, Zaatharen's cards (rev. b) dont have any caps on C101.

Another question if is possible use eletrolitic caps.

Retro rig 1: Asus CUV4X, VIA c3 800, Voodoo Banshee (Diamond fusion) and SB32 ct3670.
Retro rig 2: Intel DX2 66, SB16 Ct1740 and Cirrus Logic VLB.

C101 is 10uF 16v , not sure what other cap you are talking about though

''zaatharen's'' card is missing a cap too, you can see from the solder that one was there originally. Most of the time a voodoo1 can work fine without such a cap.

asus p5a, k6-3+ @ 550mhz, voodoo2 12mb sli, gf2 gts, awe32

Soldered a eletrolitic cap. Windows 98SE autodetected and showed like this on Device Manager:

I haven't tested with games.
The main VGA is the AGP Banshee, BX 440 board with P3 500 mhz.
Another question: Just using a VGA cable extension (male-female) will work with a 2d card? Even using VGA switcher?

yes, a thicker/shorter cable will benefit the screen quality in most cases but any fitting cable should work.

Ferrites will also help to reduce noise/coat waves. Some VGA pass-trough cables had them built-in.

Also, some other caps were mentioned in this thread (no warranty for correctness): Diamond 3dfx Voodoo 1 problem!
