I obtained my first amateur license WN7VZW in 1953 and have been more or less active in all the following years. I have not used this amplifier however I have owned it for 10 years of so. In 1963 I built an amplifier using (4) of the some tubes (572B) and used it mobile for a number of years. It really put out a big mobile signal. I still have my home brew amp but have not used is for at least 38 years. Maybe I will get it out an show it on Youtube. RF amplifiers are one piece of ham equipment that can easily be built or worked on with out many special tools. The HA 14 is sure as simple as it gets and works just fine. I found many reviews doing a Google search and most all were positive and from hams using the amp. The specification on the amp are below.
