Part 4/11:
Next, the focus is on an interesting, albeit somewhat disheveled, vintage RF amplifier final stage. The unit, featuring large vacuum tubes and triodes, appears to be built long ago but not with the best stabilization. Loose parts are identified, and the builder’s efforts at stabilization seem lacking. To reinforce it, the narrator proposes attaching a piece of metal or wood to secure the components and gluing broken pieces with strong adhesive like crazy glue, suitable for the type of material. The amplifier appears quite powerful, capable of producing around a kilowatt output at frequencies near 80 meters, which is significant for amateur radio enthusiasts. The mention of needing an RF amplifier to drive this setup indicates the technical expertise required to operate such equipment.
