Wide has two 250 kHz GDT ceramic filters and narrow 3 250 kHz GDTs.

The tuner has the better ICs of the time with the HA11225 IF/quad detector feeding the HA11223 MPX.

Twixt them is an interesting 200 kHz notch/LP filter and discrete buffer.

Audio stages from the MPX consist of discrete buffers (lots of those in this tuner) to pilot notch filters to a 4559 output IC.

Some claimed specs: IHF sensitivity 13 dBf; 50 dB quieting 41 dBf in stereo; S/N 65 dB; THD 0.12%; and separation 50 dB, all in stereo.

Measured frequency response was -1.4 dB at 20 Hz and then -0.20 dB to +0.35 dB, 40 to 15 kHz. De-emphasis time constant was 70.5 µS.
