Usage in Arcade Cabinets
The Used Toshiba Chassis PE0493 is highly regarded for its visual quality in Japanese cabinets.
It is often interchanged with other Toshiba models like the PB9929.
It is crucial to verify if the tube is a Toshiba or Matsushita (Beijing) model, as some capacitor values differ, as discussed in Arcade-Projects Forums.
