Quality of Magnavox TVs immediately following Philips takeover

[zenith2134]

For the most part, were late 70s magnavoxes improving or worsening? I think Philips can hold its own against many others, at least back then. I have 2 Philips-made magnavox sets- one is a 1984 13"color, very nice picture and never needed work, and a 1978 12"B&W that I found, and fixed the vertical sync, which was rolling uncontrollably.

What year did Philips take over? The 1978 portable says it was made by Philips Video Corp, Taiwan ROC For the Magnavox corp in Fort Wayne, Indiana and the 1984 13 incher was made by GTE in Greenville, TN. Someone help me understand this please...I'm interested because I rarely see any Vintage Magnavox--Is this due to inferior quality?

EDIT- Forgot to mention that the 1978 set has better build quality than the newer one, despite being a cheaper and smaller black and white tv. It has metal knobs as opposed to plastic junk, and the chassis has more metal.
