The Selmer TV20 was a 20-watt iteration of the TV series, offering a step up in power for musicians who needed more volume than the TV15 provided. Its valve circuit retained the clean, balanced character of the series, making it suitable for guitar, keyboard, and vocal reinforcement. The TV20 bridged the gap between Selmer's student and semi-professional offerings.
