Can you amplify an amplified signal?
It’s impossible to multiply the power of an amplifier by connecting it to another. This is mainly because of the input that you would need to send the output of one device to the input of another, which isn’t designed to handle that amount of power.
What is frequency tuning in Class C amplifier?
A class C amplifier is bias for operation for less than 180° of the input signal cycle and its value is 80° to 120°. Less than 180° (half cycle) means less than 50% and would operate only with a tuned or resonant circuit, which provides a full cycle of operation for the tuned or resonant frequency.
Is A Class D amplifier better?
Class A design is the least efficient but has the highest sound fidelity. Class B design is a little more efficient, but full of distortion. Class AB design offers power efficiency and good sound. Class D design has the highest efficiency but isn’t quite as high-fidelity.
Should you amplify door speakers?
Should You Amp Your Door Speakers? Generally, car door speakers will need amplifying. Cars typically use passive speakers, which means the speakers don’t actually have a power source themselves and rely on the amplifier to provide their power. For this reason, most car door speakers will need an amplifier.
Can You tune an 811A tube amplifier for peak?
You may not know the actual power but, with care, the amplifier can still be properly tuned for peak. With 811A tubes, while using CW, FM, or RTTY modes for tuning, always limit transmitting time to no more than 5-seconds transmit with a 15-second cool down.
How much power does the al-811h have?
The AL-811H is rated at 800-watts PEP voice on a good peak reading meter. The AL-811H is rated at 600-watts CW carrier in normal CW or tune. The AL-811 is rated at 600-watts PEP voice, or just over 400-watts carrier in normal CW modes.
How much power can Ameritron 811’s push?
While a few people are critical of the AL811 operation, every 811 amplifier throughout history has pushed 811’s a similar amount. Ameritron actually pushes the 811 tube no more than Collins or Heathkit did, both of whom allowed 1000 watts dc input on CW.
How hard does the 811h push tubes?
Keep in mind however the 811H does not”push” the tubes any “harder” than Collins did in the 30L1, or Heath did in the Warrior. It has been a long standing tradition to run 811 tubes at about 250 watts dc plate input, which is about 150-175 watts RF on the anode, per tube.
