Sorry, 我暫時唔會join , 除非塊PCB lay 埋 CCS (constant current shunt) 果 part.依家線路單靠 voltage regulation 去點燈, 睇怕唔夠穩定咁播。 師兄您話呢?

probably, u're on the right track ! {:1_351:}
a linear requlator, then, a programmable post-constant current shunt, having the LM317/LT10xx married with TL431. {:1_343:}

32sr2 max draw 25ma current...兩聲道50ma... 做balance 4粒100ma max 就搞掂。應該一組317+431就搞掂。。。

先上電阻
上埋d through hole 砌電源板。。。
砌唔煩，調音就調左好耐。
大大小小不同牌子的日系及美系德系電容都試過。。。暫時系甘先。。。
