I love portholes. I have 2 Zenith portholes and one Raytheon porthole.
If you are looking for a relatively easy to restore porthole, I would recommend
the Raytheon. Mine had a very uncluttered chassis and the chassis was
stamped with tube numbers like it was intended to be a kit.
Here is my restoration thread for the Raytheon porthole TV:
