I got a non-working gyruss pcb that looks like a couple parts were scavenged off of it. Looking at the schematic, there should be 2 ic's on the sound board, I only have 1, the other spot is empty. The schematic lists both as LA4460, the one in place is a LA4461, which I understand is a mirror of the 4460. Can anyone check what they have on a working pcb?
 
How 'bout a pic?

Yeah, Gyruss is stereo. If you only have the LA4460 at 6E it'll work with a "konami classic" to jamma adapter.

Sure, Ill nab one when I get home from work. It is the 2 ic's at 6E and 6F on the top of the sound board for reference.

I cant actually see mine as I have the heat sinks on them and I REALLY love this board so I don't want to risk anything with it. But both of those chips should be LA4460's.

If you're not running it in a stereo cabinet there's a jumper just below the audio amps (2PA on the board) if you tie those two posts together it becomes mono (with all the sounds on one line).

The board should run fine (minus audio) without the sound amps, though.

So it is supposed to be the 4460, not the 4461 then? If so ill order 2 NTE 1390's

I also have a few missing caps from the main pcb that I need to replace, so ill be waiting on a parts order regardless. Just figured id try and get these sorted while im at it. Should be a fun project!
