Yes 55er but is it dealer assy? Where does it mount and is it missing parts?

Thanks

It's the power supply part of every 1956 Pontiac radio, not a dealer accessory. Mounts behind the dashboard on the passenger side of the car next to the radio receiver. It looks like it's missing a vibrator, an OZ4 tube and a round foam rubber pad that mounts in front of the speaker to cushion it against the dashboard. In 1957, Pontiac radio speakers were mounted on the floor above the transmission hump but this is a 1956 unit.

All radios were accessories in those days, you either paid the factory or the dealer to install it.. If you didn't order it one way or the other you got the omit plate commonly called a delete plate these days.

The 55er nailed it.

 

Missing parts? Sort of. I can see in the picture you have the two 12v6 tubes present. You have empty sockets for the vibrator and the 0z4 tube. The 12v6s are the power output section of the audio amplifier, and the 0z4 and the vibrator are for a power supply that makes the higher voltages needed to operate all the vacuum tubes. The white and red tag also shows the tube layout of a radio chassis using 12ba6, 12be6, 12bf6, and 12au6 tubes. No sign of the radio chassis here other than that tag.
