Sony TA-1055
(march 1973 - 1975+)
Sony TA-1066
(september 1973 - 1975+)

The small ones, made for those who wish to not fiddle before listening to their favourite piece of music.

As per Sony's then current numbering scheme, the 1055, lower-numbered, is the bigger one... The main differences are a supplementary input (Aux.), an IC preamp stage and an effective external heatsink on the back.

Both are DC design, both had a stock wood-enclosure and both are very good-looking, the 1055 especially - perhaps more than the big separates Sony had then available... can't have it all !

A miniseries of two which, in Japan, was augmented by two : TA-1070 (june '74) and TA-1090 (july '74).
Made to be mated with the ST-5055 and ST-5066 tuners - equally unpretentious, equally good-looking :)

Not many Watts per channel but these were 1970s Watts and they still are !
