Need help with electronics (keyboard amp repair)

[SappySE107]

Its a capacitor thats blown, and I have the schematic but I dunno what part I need. Its a small brownish orange round capacitor with a rating of 0.068. Anyone know what I need?

Is the 0.068 the only thing you can read on it? Or is that off the schematic and you can't read the blown one?

that is the schematic. couldnt read the part itself

Got a pic of the schematic showing that part? Perhaps a pic of the part itself too?

I can't take a good picture of the schematic at all...i need a scanner. I do have a picture of what this little bugger looks like though. I need to resize it and thats on my desktop, not this laptop. Ill upload a picture tomorrow.

its just a 0.068mF ( "m" is actualy a mue which is a fucked up U but pronounced Micro, mF means Micro Farad) ceramic disc capacitor. SUPER inexpensice just a few cents. It may be a 0.068pF (pico farad) capacitor but that would be very tiny.

I can't seem to find a .068uF cap in the ceramic disc config. I was looking earlier while talking to Ben. Found a 0.0068 one, but that was it.

Well like I say it could be pF

In which case it will be real small

Got that pic ben?

If it is in fact a 0.068uF cap, you could always add a couple in parallel to come up with the correct value. Might be easier that way. Cause I've been looking all over the net and can't find anything that size (uF or pF).

Ok, if you look at the bottom, there are 3 orange discs. Its the size of the 3rd one up, small. When I go to warsaw, i will tear apart the other roland amp and see if I can get some numbers off a non burned to hell capacitor.[/img]

If it is .068 microFarad, Mouser has 'em.

50v rating, but they had them up to 200v that I saw. Not sure what kinda voltage that part of your amp would see, at least not without seeing a detailed schematic.

Now as to whether or not that's really what it is...

[SappySE107]

ok, who wants the schematics to look at for me? Ill mail it off monday to whoever would be so kind to figure this out for me

[RidgeRunner]

Eh, I'll see what I can do if ya want.

PM me with your address and ill get this out tomorrow. Thanks!
