Rescued a Sylvania Superset!

[TUD1]

One very weird thing about this set, is that it does not turn all the way off when you push the power button. I can faintly hear the horizontal running, and there is a very quiet sound through the speakers. What gives?

It's the standby supply - I used to have the training nomograph for the SMPS in your set. Philips addressed the low level oscillator noise with "it's normal."

What is the specific chassis?
