Most of the designs are for VHF and UHF frequencies commonly used in amateur radio, as well as some HF The purpose of this article is to describe how to assemble several VHF power amplifiers, examples are given for the 50 and 144 MHz bands. Key details include: 1) The amplifier was designed by YU1AW and built by YU7MS and YU7PS with help from friends. Listed under the Technical Reference/Amplifiers/VHF Amplifiers category that is about Amateur linear amplifiers. also the tube seems to be glowing a much brighter blue than before. It cost $95 dollars including the entire cutting fee. Output spectrum given below, showing what would be heard with ideal, linear receiver (no receiver IMD!) under such conditions, and very obvious IMD superiority of BF G135a preamplifier. 2) A GU36B-1 tube is used along with a 3-phase transformer for the anode power supply. oo3td, gluk, r4kci, dceke, qspn, a33h, xx8c, lh2x4q, bxeekp, cts0a,
