well i had so much problems with 20's years commodore psu ,i have a lot broken ...i made mine (to my opinion) a commodore psu can be re-use for a simple sid where the cost is part of the projet .... for 8 sids anybody can spend a bit more money ... and what about people waiting for wilba's sids and smash'pcb and never had a commodore ? maybe the new pcb will have a second rectifier ? c-64 psu sucks !.....i'm joking...it's always good to recycling as long as it works ;)
