On this page you will find multiple AM tube transmitters along with their schematic diagrams. I've progressively detailed my efforts to build a high quality tube-type AM transmitter, starting with …

May 6, 2025 · You could build a 6888 transmitter. Schematic is available on this forum. You do not have the required permissions to view the files attached to this post.

Below is a schematic of the transmitter as designed by members on ARF. The circuit is fairly straight forward for a transmitter but there are some noteworthy features.

In these pages, you'll find complete building instructions, schematic diagram, parts list, and an explanation of how the transmitter works. The Li'l 7 can be built in an evening or two by …

It's worthwhile discussing the basic reactance tube circuit in a bit of detail, because its principle of operation is not immediately obvious, and it is a very critical part of the transmitter circuit. The …

Most parts used in this transmitter are still available (e.g. Surplus Sales of Nebraska http://www.surplussales.com) or can be salvaged from old radio communication sets.

New tubes can be ordered from. The circuit is self-explainatory and should always be used with proper output load. The transmitter takes about 10W DC in and puts about 5-7W out. …

Apr 21, 2019 · Hello, I want to build a household tube transmitter for the fun of it. I have an SS Tran 3000 but I want to challenge myself and make one with tubes. This will be for local …

Below, you see a new 7 pin tube socket for each of the new tubes and the ribbon cable tying the original socket to the new one. Of course, I could only use one tube at a time.

Feb 4, 2023 · The coil shown in the schematic covers the AM broadcast band fairly well, when coupled to reasonably short antennas (~10 feet long). Sound quality from this transmitter is …
