Description :
The earlier Armstrong 222 all-valve amplifier (reviewed in October 1964) is essentially the same as the later model 221 amplifier. The Model 222 does not have the Model 221's addition of transistor booster stages for a low sensitivity magnetic pickup and a few other refinements but some people still prefer the sonic sound quality of the 222. Both versions are available in chassis form or in teak cases for free-standing on a shelf. The smart styling of the current range of Armstrong units has won them a Design Centre selection. The grey, silver ringed control knobs are each mounted at the centre of a greenish grey square on the front panel. There are five knobs to control input selection, volume, balance, treble and bass. The remainder of the controls are common to the Models 221 and 222 and include a rumble filter slide switch (at the rear of the chassis). The amplifier proper employs an ECC83 double triode and two ECL86 triodepentodes in each channel. In terms of sound quality, the Model 222 has top end high quality sound of a tube amplifier - neutral sounding and musical to the ears. There is no harshness in the sound. The listener can spend hours listening and won't feel the fatique. There is a certain degree of dynamics and punch that gives the life to the music. When playing pop music, the listener can enjoy the rhythm and pace as expected without being disappointed. Though a vintage amplifier, it's one amplifier worth keeping.
