Luxman T-4

Part of the pre-modern Luxman, before the classic-looking C-5000a or L-58A, the T-4 was built by SONIC, a regular late 1970s Lux contractor for tuners who also built the T-12, T-50A and quite a few others.

Inside are CLL, PLL and AccuTouch circuits : CLL to tie all tuning circuits together (from input to IF and detectors), PLL to do what was done elsewhere and everywhere, AccuTouch to focus tightly on the desired tuning spot with a tuning locking becoming active once the tuning knob is released.

Mos-FET RF stage, 5-gangs, special Quad and transformer for the IF stage, separate tripolar filters for the MPX section, wide/narrow switching (two pairs of LC or ceramic filters), plus the addition for the EU models of an anti-birdie tripolar filter.

A welcome 100 Ohm low output, too ; the matching amp is the contemporary L-4.


A real (japanese) silver T-4 here and a black one here as well.
