1940's Meissner Model 8-C FM Tuner and Thordarson Model T-32W10
Audio Amplifier
This is late 1940's Meissner FM Model 8-C FM Tuner (no audio amplifier) and Thordarson
Model T-32W10 Audio Amplifier (year 1949). The dial of the tuner is calibrated in both megacycles
and station channel number (channel 200 to 300). The tuner has 8 tubes and is
quite sensitive and selective. It requires a 300-ohm balanced FM antenna
for best performance. The tuner is monophonic only - it is not stereo. FM detection
is accomplished with a ratio detector. The intermediate frequency (IF) is 10.7 Mc.
Below is a description of the tuner from a Meissner catalog (catalog #54-B). Note that the list price with the
wooden cabinet is $110.
The Thordarson audio amplifier has 4 tubes and 3 controls: volume, treble, and bass/on-off.
It has one high impedance input marked Phono-Tuner. The amplifier has an additional
octal socket to accomodate a Thordarson Model T-32W00 plug-in preamplifier and equalizer
(that I do not have). The amplifier can accommodate speakers of 3.4 to 4 ohms, 6-8 ohms, and 15 to 16 ohms.
Only 1 Volt of input signal to the amplifier will produce full output (< 20 W).
Below is a description of the amplifier from an advertisement in the June 1949 Audio Engineering magazine.
Note the list price is $55.
Meissner also listed the amplifier in their 54-B catalog. Note the price is $82.50.
