HF Linear Amplifier Pair 813 Legal Limit+ HAM Radio hand built
Here is a very nicely built HF Linear Amp that runs a pair of 813 Beam Tetrodes in a grounded-grid configuration. 50 Ohm SO-239 input & output sockets.
Onboard mains power supply using Toroidal transformers for high-efficiency. If you are using a valve rig as the driver, it's easy to match to the input by just using the transceiver Tune & Load.
When using a solid-state rig, I used a small ATU. Either way: This is a powerful beast!
