I have spent many of the last twenty years designing state of the art high power amplifiers for a variety of uses and state of the art real time antenna measurement systems. I've never seen a Bird in a design lab. I'm sure they are great for field measurements, but your statement tha...
There are a number of military surplus "brick" multi-band (VHF/UHF) power amplifiers aka Tactical Booster Amplifiers on the market that maybe can be used in the ham bands. They are commonly about 3.3" x 2.5" x 8" in size and weigh about 3 pounds. One is theKMW1031rated at 20 Watts...
on performance. **Versatile Application Scenarios** The High Precision Amplifier is suitable for a wide range of applications, including repeaters, BTS high power amplifiers, WCDMA LTE, GPS, ISM, and more. Its broad operational frequency range makes it a versatile choice for various wireless ...

A problem exists in all vacuum tube power amplifiers when the input signal reaches the point where the driver tube attempts to drive the grid of the output tube positive. You say that your amp operates in A1 and that won't happen. Wrong! Unless the driver is carefully designed to clip be...
Quote from: Audioguru on November 25, 2016, 02:08:12 am 240V into 500k is a whopping power of 0.12W. Then why use a 100 amplifier when a 1W amplifier is plenty. Most of the low power amplifiers are also low voltage. The $3.65 delivered price in a ready to use format motivates me...
Yes, you can use corded dimmers just fine with the sine wave output, as well as drive traditional electronics with power transformers, and even classic vacuum-tube power amplifiers like the timeless McIntosh MC240.The AC outputs shut off to save power if less than 10 W is used for more ...
