Although the TDA2030 can deliver 20 watts of output power, I deliberately reduced the output power to about 8 watts to supply 10 watt speakers. Input sensitivity is 200mV. Higher input levels naturally will give greater output, but no distortion should be heard.
For 160, 80 and 40 meter bands. With 58N20s it will deliver 400W on 40 and 700 on 160/80 meter band. The amp needs 25/35W of drive for full output.
With the amount of equipment in home entertainment centers today the need to be able to vary the gain of the audio or video signal is needed. It can give 3 outputs from one input
The basic function of a power amplifier is always the same: to boost a low-power signal to a higher power level, to be delivered to the amplifier load.
The unit is powered directly from the 120 volt AC line, with no power transformers.
FM radio and VHF TV amplifiers.
7 type of vaccumtube amplifier. 6AW8A is the best tube to the audio amplifier of amateur radio. 38dB is best gain of all the circuits. 390mW is enough power.
There are all sorts of tube circuits, some of which actually deliver The Sound people associate with Vacuum Tubes.
Is this a project or an article? Since you may have arrived here from either index, you might be a little confused. This is fine, as it has elements of both, but lacks the in-depth analysis of other articles, and also lacks the application of a final design that is common to my projects.
