Capcom QSound Amplifier

Variants

There are 2 known variants of the QSound amplifier, both share the same reference CPB-001A, which can be confusing.

• The first revision is used in Capcom Q GrandAm 25 and US "Big Blue"cabinet and needs 14VAC to work properly.
  
• The second revision is used in Capcom Impress and has been modified to work with 12VDC and therefore doesn't need an AC transformer to work.
