What a shame. Beauty is only skin deep, but ugly is to the bone.

Yeah, Ive seen and done plenty of rework in my time, but that is just nasty. Not that big a change, either.

I am experiencing the same imbalance between my L and R channels at low volumes with Dayton APA150. I know its a different amp and all, but the build quality is probably on the same playing field as the DTA100.

hmmm, so its pretty much pointless to send it back for exchange. its either return it or mod it with better components.

anyone know where one can buy a better quality pot?

British Columbia - talk to some of the college kids. Just kidding, check out Digi-Key. They have quite the selection.

received one of these as a sample. Volume pot really is trash. Had a major imbalance between channels and the crackling sound as the volume increases/decreases isnt a good sign either. Apart from that, its quite good. Will get manufacturer to utilize a better quality volume pot in this amp.

The new amps that Parts Express is selling from Sure will be much better to choose from.

Imbalance in very bad at any volume level. Volume pots are usually the cause at low levels? Any help would be appreciated.

Try a different pot or wire the input to by-pass the pot and use a pre amp or digital volume control to hear if it is then balanced. Measure the dc offset between each pair of speaker terminals to see if the output chips are still ok. I don't have one of these amps so I'm not sure of the circuit that they are using but I haven't read anything good about them. Maybe Parts Express will just give you a store credit for a refund without having to ship the amp back. Then you could buy one of the amps from Sure that they sell or, one of the ebay amps from hifimediy which are much better.
