Description
The JVC AV-27D302 is a 27-inch CRT television from JVC's D-Series lineup, released in 2001. This middle-era D-Series model features the GE chassis with Toshiba TB1253AN jungle IC, 3-line digital comb filter, and component video input. Like other Dx02 models, it uses a 1.2W mono power amplifier rather than the 5W stereo amp found in earlier D-Series.
Design
The D-Series features side-mounted speakers, giving it a wider footprint with better audio separation than the 30 Series. The AV-27D302 was available in black cabinet finish, transitioning to silver with later Dx03 models.

- B = Goldstar/LG
- M = Matsushita/Panasonic
- H = Hitachi
- Y = Toshiba
