Hey there guys, so I recently bought a Pac-man Cab from arcadefr34k, and It was non-working. When he originally bought the machine, everything worked, including sound, he sold it to me when the game stopped booting. It's working now, but the sound isn't. Back when I was trouble shooting, I removed the audio amp to see if it was bad, because I had fuses blowing. I lost the amp, but reordered an LM377N. It just came in today, and I installed it. Sound still isn't working.
This is an exact image of the chip i bought.
I put the dot towards the U on the silkscreen. Is it possible I got a faulty chip? Becuase none of my pins are bridging, and I have continuity through all the pins.
Thanks in advance,
-Cody
EDIT: If it matters, I'm getting around 1.5VDC coming off of the 330uF Capacitor, leading into the LM377N. I'm not sure if that's low or not...
