Title: Speaker issue!
Post by: Flynn's will live again! on September 25, 2013, 09:01:39 am
Hi all,
       I'm working on a tetris upright restore and I just replaced the mono speaker and for some reason, sound comes out but I need to hold the speaker to my head because it's so quiet. I'm not new to wiring but am new to speakers. The original was a 5.5 in 4 ohm 7watt speaker, the replacement is a 4 in 4 ohm 8 watt speaker. I was told ohms was what you wanted consistent so I thought this would work. Is it the speaker? I can hear the game just really quiet. HELP!!!!!
       Thanks much all!

assuming you have checked the volume settings on the board. I would re check all the connections and the wire then if that's all good I would test the speaker on something else a  small stereo or something. If it works fine then you have a problem with your PCB and if i had to guess it would be most likely the caps
