Hi Need help. I am doing a QTB on a strat, and have a problem that is holding me up. I cannot find a 0.33uf 400v metal film capacitor anywhere. Is there an online site I can order some? Thanks

Tandy, Maplins, Radio Shack, Stewmac, Axes'R'us, allparts, try google search for capacitors, try google for hobby electronics supplies, should not be much trouble finding somewhere to get yourself the right cap.

Al,
the first 3 are good candidates, because they are general electronics parts suppliers.
but, i doubt you will find any 400v rated caps at a guitar parts house.
cheers,
unk

digikey.com
They have a 1,300 page+ catalogue of electronic components.
For orders under $25, they have a $5 handling charge. That's never been an issue with me since I have difficulty spending under $25 with them.
While they don't have electronic components for guitars (specifically), they do have many components that can be used in guitars. They're not musical instrument specific in any way, but are the prototyping "salvation" of electronics engineers.
I've been using them since the very early 70's.

Thanks for replys. I did try radio shack immediately, however they only went up tp .22uf.

You could try a 0.22, it will give a different bass/treble range to a .33 but yiou might like it

flateric - most probably hdcorvette is referring to the isolation capacitor used to block high voltage dc in the QTB, rather than the tone cap (which would normally be 0.022 to 0.047, rather than 0.22)
For the isolation cap, not many guitars have them, and the alternative is just a wire link from the bridge metalwork to ground. If you want this safety feature however, and can get lower values in that 400V rating, put two 0.15 in parallel which will make 0.3, which is near enough.

John was correct. I am looking for a.33 capacitor for Isolation. As the QTB suggests, I am looking for safety. I appreciate everyones help. I have done google,called local suppliers, and still cannot locate what I need. Has anyone bought these capacitors recommended in the QTB, and where did you get it? Do you have a stock number? Digikey did get back to me, as a result, I have another question. The QTB mentions using metal film capacitors. However digikey told me they have plastic and metalized poly propylene. Does it make a difference in the material the capacitor is made of? Also I was on the guitarnuts site a few minutes ago looking at some strat rewiring "S-Tastic"and the writer suggests using a .33uf 450v cap for isolation. Now I'm not sure which cap to use, because this is a contradiction to his QTB specs. I would appreciate more specific information, so I can get the correct parts. In the"S-Tastic he mentions using film type capacitors in the rewiring. Are there certain materials they should be made of that I should be looking for? I need to get my guitar back together soon! Thanks for all the help
