The horizontal output tubes for some years were popular for illegal CB Radio not so linear amplifiers, and for many amateur radio HF transceivers as well, the Yaesu FT 101 line, the Swan 350 as two well known examples. They were cheaper in this era than Eimac 3-500z or other RF tubes when these transceivers were new, or not very old.
