Good design, transformer with adequate load regulation (18 vac no load, 15 vac full load), 300 mV ripple at bridge DC output (full load). LM317T/LM337T with non isolated heatsinks meets easily load regulation and ripple rejection. Pay attention to strip input connector to not fry the transformer, common point is exposed as input too. Adequate delivery time, comes in antistatic bag but it really needs a cardboard under PCB to avoid bag puncture. I recommend the product

In the end the device has not yet checked, but "on the table" work. Do not warm, do not beep. The Blue led in the assembled device will be superfluous, although it is convenient for debugging.
My recommendations.
