Minim Electronics Limited marketed a range of three decoders, the AD 7, AD 8 and AD 10, and also a printed circuit board module for enthusiasts to incorporate into their own projects.
IMF Electronics assisted in the development of Ambisonics and manufactured a decoder, the D20B. Part of the company was resurrected under the name TDL Electronics Limited, but it is unlikely that they have had any interest in Ambisonics.

Up to 1981, Integrex Limited offered an Ambisonic decoder which could decode SQ, QS, UMX and Matrix H/HJ as well as UHJ. The Company is alive and kicking, but no longer has any involvement in Ambisonics or the hi-fi business.

Mitsubishi developed a home-theatre pre-amp, the DA-P7000, which incorporated an Ambisonic decoder. The prototype was displayed in Abbey Road Studios, United Kingdom, in 1991. Does anybody know if it was ever offered for sale?

And one for our antipodean readers; Audiotech Industries offered an Ambisonic decoder. Details anyone? The phone is disconnected and the company is not listed in either the 1996 or the 1997 phone books.
