One channel is louder than the other?

Well, I went and replaced the resistor.....and still the same problem 😡

I even re-soldered all the connections on the board....still no luck. I tried connecting the input directly to the board (with a 10k resistor in series) , but that didn't work. I'm running out of ideas aside from the chip itself. But as BZ said, this typically wouldnt be a problem with the chip?

I'm at a loss 😕

Might be easier just to get a new one than de-solder both of them...I think I'll put in an order tomorrow...

Plus, I don't want to mess up the working channel if at all possible 🙁

Drop me an e-mail with what parts you need, and I can ship out some replacement parts for you, instead of having you buy a whole new kit.

Yea...I tried every combo I could think of and still no luck. Kind of an odd situation eh? At least I have a premium kit coming from Brian in a week or two (crossing my fingers) to build another GC with 🙂

Brian: much appreciated, but I already ordered another LM3875 from Digikey...I need some other parts anyways and threw it in. Thank you though...your generosity is dually noted. I wouldn't think it would be a problem with the board itself, so we'll see what happens when I get this new one in there.
 
Just to make sure again that I have set things up correctly, here is the current setup for anyone to comment on. I can connect the speakers directly to the outputs on the board, and I still have the same problem. Also, the pot tracks fairly well between channels...it's only about 200~300ohms off. I hope you enjoy the Visio picture...it's all I have at work 😀

Your diagram looks correct. I wish you best of luck for getting it working soon 🙂

Well, I replaced the chip and...no luck :bawling:

I'm really at a loss for the moment...I think I might leave it alone for a bit and come back to it...it's getting to be really frustrating 😡

As they say, back to the drawing board...
