In my recent post christmas shopping spree... I picked up a new 43" inch TV for way way less than I paid for my old 27" years ago. For the first time in recent memory I can see the score and shot clock during basketball games from across the room, but I can't get over the crappy sound (sounds like it's coming from an orange juice through a string).
They claim 8W amps inside, but I am reluctant to take it apart and grab external speaker feeds, they're probably heavily equalized and not very usable. I maxed out the internal bass boost that helps a little but still sucks.
Time to come up with a low impact amp.... I can't see turning on my big dog amp every day just for TV. I have plenty of speakers laying around. I might flesh out an idea I have for a class Ab output stage design (using my 3 device long tail pair***), at least to use this winter. In the summer I can just reduce the class A bias.

**** hypothetical amplifier is technically class AB, but output devices never cut off below a defined class A current, so crossover transition occurs in a low level stage before the output devices. This class A current can be set arbitrarily high which is why I use big A and small b in class Ab. Note: I have seen japanese patents doing similar trick, but not using my 3-transistor circuit approach. IIRC they used steering diodes but I haven't looked at the patents for decades.
PS: I have a computer speaker rig with 4 speakers and amps and a sub, that I may repurpose for the TV. I moved my old TV over to my computer desk so I can use the speakers in for web listening.
