Jerry:
As 50s portables go, that is definitely one of the better ones. The "U" designates UHF, somewhat rare for the period. It is well designed and constructed using a power transformer and 5U4, so the chassis is isolated from the power line. It uses a 14RP4 CRT. That's a 90 degree electrostatic focus tube. It also has a solid retrace blanking circuit and a good RCA tuner.
The 90 degree tube and power transformer will make the TV somewhat heavier than many other 14" portables of the era.
It is relatively easy to work on, particularly when compared to the later 50s RCA portables. If not already done, it will need a few paper caps replaced in the vertical and sync circuits and some tubes in the signal processing circuits. When working properly it will provide a sharp steady picture and clear, buzz-free sound. Make sure knobs and trim pieces are intact. I would not be afraid of this one.
