* Weitere Komponenten der Laboratory Reference Series waren nebst der Endstufe 5M-21, der 5G-12 Graphic Equalizer, der 5F-70 Parametrische Klangregler sowie die 5E-24 LED Pegelanzeige Einheit.
−
* In 1977 and 1978, the Luxman Laboratory Reference Series was expanded to include the 5L-15 integrated amplifier, the 5M-20 power amplifier without VU meter, as well as a less expensive tuner, the 5T-10, and the 5K-50 cassette tape deck. The 5K-50 was Luxman's very first tape and was probably purchased from a third party manufacturer (possibly Alpine).
