Reece,  looking at the schematic you need to check the jumper cable to the line out socket.

Man you're tight!

Here - maybe it's worth $3.00? Do ya squeak when ya walk?

actually it's not the money that bothers me - I don't trust those sites.  maybe without merit, but they just seem "shady" to me.

Reece Here...for only $2.00...just mail the two to me and download anytime. Two is low
as I go.




(thanks Herb)
 
 
You did check the fuse and the wall outlet didn't you?

Guitarhacker


google search turned up several sites that have it for free.

http://elektrotanya.com/roland_kc-100.pdf/download.html  this is only one of them. 

did either of you try to actually download it?  see this is exactly why I despise these 3rd party manual websites - not the actualy mfg.  try to download it.  it doesn't actually work.  it takes you to another screen which says you can download the "free toolbar" to search for the document you want.  no thank you.
 
if you click on the page itself it brings up only that first page.  I cannot find any way to actually download the real manual from that website.
 
Michael - it's not going to be the fuse or the wall outlet - because as I said it's ONLY the LINE OUTPUT of the amp that doesn't work.  the amp works fine otherwise.

Karyn - thank you!  where are you looking at the schematic???  I need to see where that jumper is.

I'd open it and look at the line out jack and look to see if there is a burnt looking resistor near it but don't touch anything other than the jack with your hand. It is a good idea to keep one hand in your pocket when poking around in an amp. Anyway, maybe a wire came loose on the jack, especially if it is working otherwise.
Good luck and be careful.

thanks for the advice Julien. yes, I'm quite aware of safety.  by day I'm a Test Engineer (EE), so I deal with things like that all the time at work.  that's why I should be able to do this myself if I have a schematic.

I agree about those sites Beagle. Ive found a couple manuals on those sites I passed on. 

As for your amp ... I dont know how old it is, but it could be something as simple as a cold solder joint, or blown fuse. Especially those surface mount ones thqt they make to look like resistors and diodes. The other thing, try a different cable and keyboard.

Usually if you have speaker output but no line output, its something simple. 

thanks bub, yes, I plan to try to look for blown resistors, fuses, bad solder joints (harder to find) and diodes.

but it's not going to be a problem with the keyboard or input cable since I can use the amp normally except for the line output.

but I did try a different cable from the line output to the board.  that didn't work - that's why I am sure it's a problem inside the amp with the line out only.

WAIT!  sorry herb & Michael - I found the place to actually download the manual on that page!  it's the little link inside the paragraph.  

downloading it now.  thanks again and sorry for bustin' yer chops about those sites.

Personally, I'd start off by eating some becan.  It may not cure the problem, but I'd feel better about it right away...

(And, I'm lucky, there's a very good repair shop in Portland for exactly this type of stuff!)
