LT1084 等會比7812好
Roy 兄的亦是好野，應該有起動延遲

Your PCB bought from taobao I also had one but not yet use.
Mind one is 2 CH PCB and Transformer(50W) is Dual output with two difference output (7.5VAC & 14VAC) so that I can use High & low voltage with minimum heat loss.

It doesn't have Power up delay but I add AC Line Filter to reduce noise.
I made another power up delay PCB just arrive but not yet check.
