the PCB is not consistent with the given parts. I miss 2 capasitors 220uF 10V and a cool. and a 332. and I' left with some parts which I cannot find a Palace to put them on the board. very dissepointed.
I bought 2 modules of the DIY version. there were a few extra small value capacitors and 2 missing chemicals, luckily I had some in stock. The cooler supplied with the kit is not suitable for the assembly and the power transistor must be mounted upside down with respect to the cooler, it's weird. The module works well and the sound quality is very good. The emitting transistor heats up a lot, you need a bigger cooler and put on heat sink grease. There is no knob on the frequency tuning capacitor, that's a shame. otherwise it is very good value for money and the delivery was very fast.
