Good Chinese TPA3255 board?

[777funk]

I'm thinking of putting a power amp or two in an SWR Henry the 8x8 cab (8x8" at 32 ohms each). This one seems like a good choice. I figured I'd run the cab off of two amps (or a stereo board) with each driving an 8 ohm (4 speaker) load.

Is there a good ready to use board on ebay?

Likely all very similar.
Suggest if for PA duty you rate them conservatively - just a hunch.

The majority have really bad inductors and capacitors unfortunately.

Classdaudio.com sells a 3255 board that is made in the US. It is not cheap, $185, but seems well made. I bought one and like the sound very much.

If you only want 25 watts per 8, go with a PBTL board and run it 4 ohms. Pro audio / AES power ratings, the 3255 boards that are common can only belt out around 200 watts continuous RMS into 4 ohms. The cheaper ones, even less. Expensive boards with a couple pounds of heatsink/output inductance get you better transient response and less dynamic limiting when running hot.
