YM2149F Dip-40 Integrated Circuit From Yamaha

Good if you get a good one

Most of these on sale are used/pulls from equipment.

Some have small faults e.g. they fail after a few minutes, others produce distorted sound, others arrive completely dead.

Having purchased more than 20 from various sources I've found there is no way to predict what you may end up with. The ones that look shiny and new are often the ones that have faults.

I recommend to buy a few from different sources and hope for the best.

I don't recommend to buy in bulk from one supplier, as they may all come from the same batch.Read full review
