I am looking to put together small speaker/headphone amplifier. Unfortunately, I can't use TA2024 as it is bridged so I am looking at LM1875. There are kits available from China that require 2x12-18V. Now, my knowledge about circuits is limited so please let me know if I could use 16V-0-16V toroidal transformer to power this board.
There is also kit from ChipAmp but it does not have instructions posted yet. I have built LM3875 from ChipAmp before and for CT trafo I needed to modify the PSU board. Without instructions, I will have to most likely get the one from China.
Thanks.

Hi
By looking the pictures it is suitable for center tapped transformer also.As it apparently has 3 connectors for AC/GND/AC.
When deciding between "known" kits as ones from Chipamp or kits found from ebay,be aware of the possible fake chips and components.I'm not in any means saying this kit has fake components but some may have.

It says 2 x 12-18 V AC. 2 x 16 V AC seems to qualify.
There is an entire thread about the chipamp.com kit, which is probably as detailed as any instructions can ever be.
