Default aleph´s mini output resistors smoking

hello
I completed pcbs I bought on ebay, matched all components, everything controlled twice, but when I turn it on, output resistors 0,47ohm begin to smoke after few seconds. Till then it sounds really nice
Both modules behave equally, is there some common problem I overlooked?

Are the .47 power resistors the correct dissipation value?
Best to post clear pictures.

I found out what I did wrong - I have installed bc550c wrong way, do you think it did some fatal changes to amplifier module?

if nothing else , at least those smoking resistors are for change

btw. you evidently didn't follow any usual amp setting procedure ....... so it would be nice if you search a little , how to put (any) Aleph amp in work .....
