HI all.
I allready done a barracuda MD and it works perfectly .i rebuild one and it d'ont works ( same pcb)
when i switch on i hear a long beeep (normal)
My first problem is :when i connect coil, it short circuit all the detector and tip127 is warming.
my second is :i cant tune 0v on pin 6 of the NE5584 i ve got 2.6 to 4.5v.
the icl7660 give me negative volts,7805 and 7905 do their job(i supply it with a 9 v battery)
i only change 2n5485 by bf256c (180° turned) and mpsa13 by bc517 (180° turned) and i ommit Q5, 10K,270K near the SW
Got an idea i'm lost
Thanks
