This is a stereo power amplifier transformer kit designed to complete an excellent amplifier easily with a little work.

It was sold as a kit for transformers, terminals and chassis, and vacuum tubes and CR parts were sold separately so that it can be used with parts and circuits other than the recommended ones.
In addition, a parts kit with a set of vacuum tubes and CR parts for KMQ7 was also sold.
