missing capacitor CR-840??

I wonder if someone could check their CR-840 for me... and compare to this picture. Near the output chips, I have what appears to be a missing capacitor. the one on the right in the photo has 3 in front of it, while the one at the left is missing the centre one, which is a 1uf 50v cap. There are markings on the board that seem to indicate it should be there. It connects pins 4 & 7 on the chip.

Obviously my boards need a major cleanup - I think they lived under a cat. I have this thing completely disassembled - hopefully I can get it back together!

There might be. I think I can see it in this photo (which isn't mine) here.




In your photo that area looks kind of messy...But maybe it's a reflection.

Yes, it should be there. C726. + side on the right

yep - right on both counts. messy, and reflection. This receiver looked great on the outside, but filthy on the inside. No wonder the tuner doesn't work... I'm surprised the amp did.

Perfect! Thanks to both of you. I'll be sure to put one in.

The less caps, the better.

Unless the design calls for one in a given location? I'm not exactly sure of it's function in that spot - but I'm not one to question the designers at this point!
