Price is very good. This is a fun way to try the famous diyaudio FH9. I recommend you try this design! Both boards work and sound good. Particularly good flowing bass. HOWEVER one had the bias current set WAY too high. Fortunately I was using a Dim Bulb Tester which flashed and the board was not destroyed. At only +/-18V DC the bias was 0.5A and rising! Both boards had very messy soldering (see photos). I would ask the seller to please improve the soldering. Please don't ship boards with super high bias as many buyers will not have a Dim Bulb Tester and it will blow up the amplifier. I don't believe these are properly tested after assembly. Use caution and power up with a Dim Bulb Tester to prevent disaster. Check and reset bias at a lower supply voltage first!!! It is not a good idea to ship to the other side of the planet without really proper testing. What if it blows up? It is then not fair to claim it tested good when it was not really properly tested.
I just received my order thank you very much
