siriuz 0 Report post Posted January 24, 2006 i'm more or less done with the pcb already, if i can get a drill bit tmr, then the amp should be ready by tmr night. if i can't... then its a whole different story if i can get it ready by tmr, and theres no hum or whatever issues, then i'll release it to you guys and probably on request, etch a board for a few bucks (at cost price, no profit) or so.
