Three-program receiver `` Ayan-301 ''.

Three-program receivers.The three-program receiver "Ayan-301" with a timer was produced presumably since 1988 by the Tuva Machine-Building Plant. It is intended for listening to one low-frequency program (with amplification) and two high-frequency programs transmitted through a compressed system, as well as turning on and off the receiver at a specified time and displaying the current time. In the last photo, the timer chip is missing on the board.
