magnavox astro sonic

I am looking for parts to replace the picture tube and other parts on my Magnovox Astro sonic tv/stereo/phonograph. Model #1c7644, finish maple, serial # 2404463. 365watt 117v 60cy. Not sure of the exact year, it was purchased used in the early 80's. I have looked all over and cannot find anything...any info would be a great help. Please email me at ariray496@wmconnect.com please put tv in the subject line as i share this account with my wife
