Feedback paths coupled through the secondary of the output transformer reduce distortion because they compensate for the transformer's distortion to some extent.
22.
Direct current ( DC ), is switched though the line output transformer, and alternating current ( AC ) is induced into the scan coils.
23.
Visible are two glass output tubes, six smaller preamp tubes in their metal tube retainers, and both the power transformer and the output transformer.
24.
The voltage used to bias the varactor diodes in modern tuners is often derived from the flyback transformer ( " Line OutPut Transformer " LOPT ).
25.
While the combo versions sharing the same cabinet and pre-amp design, the output transformer, output tubes and single 12 " speaker differed.
26.
Radford's hi-fi amplifiers enjoyed a reputation for quality that was " second to none ", especially because of their output transformers.
27.
Tube amplifiers typically have much lower feedback ratios, and in any case almost always have output transformers that limit how low the output impedance can be.
28.
The following year, the Shure M67 mixer added an illuminated VU meter and a line level output transformer for connecting the mixer to a telephone line.
29.
Visible are two glass 6L6 output tubes, six smaller 12AX7 preamp tubes in their metal tube retainers and both the power transformer and the output transformer.
30.
The overall negative feedback is clearly seen to be applied by the resistor R25 from the secondary of the output transformer to the cathode of the input V1.
