Hey Andy did you find the remote control too? If I recall, it was an IR computer space command.
I like AKB on almost any set EXCEPT 90s-2000s Sonys which blank the raster. I had a 35'' trinitron from around 99 and the raster would just flash on and off sporadically, due to a weak red gun.
Your set looks like it was really heavily used which is cool because it still makes a great pic; with any luck the tube'll hold up fine!
My buddy just phoned me today--hes out of a town and picked up an 82 z-nith for me. Probably nothing special maybe Ill post some pics. I actually really like these sets up until about 84-85
