Upgrading an Otherwise Useless Solid State Set

[zenith2134]

Hi guys, I was bored before and was "craving" an electronic project , so I dug out a 1977 RCA Colortrak tv, model FB497W, Chassis CTC 89, CRT# 19VBHP22. It works well after I did the convergence on it (pain in my ass lol) but have always wondered how I can add-on to or modify a simple solid state TV like this and many others which I've got over time.

I was thinking along the lines of fitting in a 40W tube (or SS) amplifier and 2 or 3 speakers, (partly because I love audio so much), but I want something really awesome and cool for this one. Are there any suggestions on what types of mods can be done with TV's ? (does not have to be only an audio mod) thanks I am expecting something intriguing as usual from AK!
