Luxman T-33

Circa
1 9 7 5 c.1975
1 9 7 7 1977

Tiny 3-gang am/fm tuner, companion of the equally tiny L-30 and L-31.

FET input, linear-pahse ceramic filters, quadrature IC transformer-coupled discrimnator, PLL MPX IC and LC low-pass filter with constant voltage-supply.



No masterpiece at all, no T-110 or ST-A7B but pretty and more reliable than either big guns.
