Edited from a new product announcement in The january 1982 issue of Gramophone magazine:
Mordaunt-Short Ltd., Durford Mill, Petersfield, Hampshire GU3 I 5AZ have launched a range of new versions of their popular loudspeakers. The Carnival 3, Festival 3 and Pageant 3 all employ the company's own DSB208 bass/mid-range driver, with the benefit of a slight increase in internal volume and a change of width-versus-depth ratio to reduce colouration effects. A fabric finish offers some economy over wood veneers with no sacrifice either in performance or appearance. The Festival 3 (£197.80) is a 520 x 255 x 220 mm, two-way reflex with 25mm dome tweeter. seventiesstereo
These sound very promising so far.

Toshiba SB-404 (+ Toshiba HR-40X Stereo Phones) Four Channel PRE/MAIN Stereo Amplifier With Matrix Decoder, 1973-1974, made in Japan
4-channel Integrated Amplifier which carries a four-channel decoder.
SB-404 in is equipped with a QM system decoder unit (part of the catalog had been described as RM system in place of the QM system)
In addition, SB-404S is equipped with SQ decoder as a top model.
It is equipped with a separate pre-main circuit, it can be used as a 4-channel system as it is a discrete method When you connect a 4-channel deck. It can also correspond to the CD-4 system by connecting di modulator a (SY-504).
Pre-main circuit has become a four-system independent configuration.
The transistor in the circuit I am using the Toshiba ultra-low-noise transistor 2SC1000. It has its own due to the PCT process (Perfect Crystal device of Technology), as compared to the conventional low-noise type excellent that one-third in 1 / 2,10kHz at 100Hz characteristics.
In SB-404S uses the 27 pieces of 2SC1000 in all circuit total.
It has a built-in equalizer circuit of condenser cartridge only.
This you can use the Toshiba record player SR-80C and electret type condenser cartridge C-401S series.
The power amplifier circuit I has adopted the whole page hardwired-connection OCL type of IC power pack.
It is to prevent the deterioration of the characteristics due to the coupling capacitor by all each stage direct connection type, and has improved the frequency characteristics and distortion characteristics.
When 2-channel playback is enabled the BTL connection, you can output up by the use of four of the power amplifier.
