Technics Brochure Highlights
Linearly variable tuning capacitor, FET front end and 5-stage differential IF amplifier for high sensitivity and selectivity, and low capture ratio. Three "Flat Group Delay" ceramic filters for minimal phase distortion. Chebyshev-type low-pass filter permits wide, flat frequency response with sharp attenuation of 19 kHz pilot signal. Phase locked loop IC in FM MPX circuit for wideband, stable stereo FM separation. Test signal generator for accurate setting of levels on tape deck. Antenna terminals directly connected to front end circuit board, for excellent spurious response and image rejection. Zero-center and linear signal strength meters. FM muting to suppress interstation noise. FM linear dial scale. Simulated wood cabinet.

Have some additional information about the Model ST-7300 Tuner? If so, I would sure appreciate it
if you would EMAIL
that to me. I'll add anything: What type of controls, specifications, number and type of AC outlets on the back...
anything!
One thing, though... if you see some info and you believe it is incorrect, that is certainly
possible. However, it does no good to tell me that "I don't think that's right".
You need to tell me the correct information to replace it with. For instance, if I have that
a particular model was available 1978-1979, and you believe that is wrong, then tell me the
exact correct range and your source of information, rather than "I had one of those in 1976". Otherwise, I can't
really change the database with any confidence.
The database currently contains "slots" for many AM Tuner, FM Tuner, Amplifier and Preamplifier specifications,
as well as many of the controls and features Technics has made available on these units. You can check the Sample Unit to see all of the database slots. You
might even be surprised at some of the slots that are available. However, if you come up with something that's not in the Technics Classics database, either a specification
or a feature, I can add it in just a few minutes, along with specific details about that feature for any model(s) you know of. Don't be shy - tell me!
These listings can only be as good as the information in them. With your help, they will improve over time. Please accept
my heartfelt thanks in advance for anything you can contribute.
