Acme’s new tuner model AM-T90 came into the market in July 2009. This tuner
uses Input & Output Jacks as well as orange backlight for LCD
display. The holder on the back gives a good 45 degree visual angle,
thus with an easy to see screen when tuning. This tuner will soon be put into mass production.
