Summary
Includes S-Video, side-firing speakers, as well as jacks to power external speakers. Has internal pots to adjust pincushion, horizontal width, vertical size & linearity. Lacks controls for horizontal & vertical position (can be somewhat manipulated with purity rings, but may require a magnet(s) on the picture tube to compensate for purity issues). A downside to this chassis is that it resets picture settings when it is unplugged; as such the contrast will be maxed out unless it remains plugged in, or the user adjusts the picture settings every time it's plugged in.
Jungle chip does not have RGB inputs, but S-Video is already very sharp. The glass comb filter will not blur the the waterfalls in Sonic but rather resolve them as distinctly alternating vertical lines.

Repair Notes
One specimen had a loud hum in the left speaker caused by an open feedback capacitor C3C2. The brown adhesive used to hold down capacitor C773 was found to be significantly corroding the components it came in contact with on the main PCB. There was some minor upper pincushion, made more prominent in the presence of red.
