THIS IS NOT A MAGIC BULLET FIX = PLEASE CHECK YOUR PART IF FAULTY BEFORE BUYING.

I CANNOT ACCEPT NEGATIVE FEEDBACK IF THIS IS NOT THE MAGIC SOLUTION TO YOUR PROBLEM.

I CANNOT ACCEPT NEGATIVE FEEDBACK IF YOU MAKE MISTAKE ON THE JOB.

For sale reproductions the custom IC marked 'HB-45A'. 

The reproduction, designed by me, will substitute the custom IC marked  'HB-45A' used on Seibu arcade PCBs like:

•  Raiden II/DX
•  Zero Team

The replacement has exactly the same functionality of the original part which is known to be prone to failure causing scratchy or no sound on PCB.
