Hello All!
I'm playing around with this TDA7294 amplifier board:
https://www.pcbway.com/project/shar..._Amplifier_with_bass_and_treble_499c51bf.html
I've completed the board and hooked it up for testing. It works, but I notice a lower output volume on the left channel compared to the right. It's not a huge variation but noticeable. My electronics knowledge is limited so can anyone suggest what might be causing the difference and what I should try to fix it? Also, is there an easy way to determine the power ratings on the SKP0228 transformer? It puts out 24-0-24. I can't find any information online. Thanks so much!

Thanks for the info. I'll check the resistance on the right and left channel of the pot and see if they are equal. I appreciate it.
I had a fault on a speaker system where one was a lot louder than the other one.
The amps output same signal level so it had to be a speaker fault.
Turned out one speaker was 8 ohms and other was about 2 ohms
I pulled the 2 ohm speaker apart and coil was partially fried.
