MUSICAL HOLD ON
A very smart circuit for having music in the telephone, when you put the caller in hold. It is a useful alternative solution for telephone sets that dont have this option.The construction is based on an IC that generates a known melody. It also gives you the ability to record your own melody from a tape player or CD. There is no need for power supply as it is connected in parallel with the phone line. PCB 57x72mm
