Problem is I know very very little about RF stuff but I can follow instructions rather well, so a kit would be great. So what's the catch?. 8MHz - 50MHz power amplifier with additional capability at 472kHz. Using Solid-State Transceivers With Older Tube Amplifiers A collection of Hints and Kinks from the pages of QST; How to Test and Align a Linear Amplifier QST May 1952, pp. Tomco Technologies today supplies RF amplifier systems to scientific and industrial customers worldwide for a broad range of applications including nuclear magnetic resonance, particle accelerator systems, radar, ultrasonics, plasma applications and HF communications. Vacuum tubes operate at high anode voltages and moderate anode currents; typically, a tube PA (power amplifier) stage requires an RF anode load resistance of approximately 2000Ω for optimum efficiency. Current is 25-40А. Had this rig for 2 years now and use it as the primary rig great receive and transmit always get very good audio reports there are so many ways to set the audio for the tx and rx you can't go wrong very sensitive receive and i have use it on am mode and its just as good as a old boat anchor and the receive is. I do not know the name of this amp, or who made them.
