TMNT PCB Sound Issues

[Frank_fjs]

It was the two tantalum caps that resolved the issue however I recapped the whole board while I was at it.

I'm having this same exact issue with my PCB. I see that @SS4Rob replaced the tantalum caps w/ electrolytic caps. @Frank_fjs did you do the same?

Is it okay to replace all the tantalum caps w/ electrolytic caps?

I would say film caps would be better than electrolytic if they are under 10uf, but best to wait for a reply from @djsheep

I need to do this to my Japanese TMNT board eventually, but last time I used it, it was perfect.
