Looking for help from the owner of an early 90s Sankyo...

[Lashujin]

So I've been working on fixing a sound issue on my Jazz Men Hanemono. I'm looking for help from someone with a Sankyo machine from the same era.

I have some pictures posted in this post from my support thread:#14 I'm looking for a similar photo to the first large one from a different machine to compare. Specifically to see if the solder filled pinhole above the number 18 is filled in on other boards.

If someone happens to own a Jazz Men that would be even better, but I'd guess the layout of boards from the same time period is similar.

Thanks if anyone is willing to help.
