What we have here is a beautiful example of a home-made transmitter. As you can see from the photos, the ham (unknown) who built this was a true craftsman. He even made the chassis and formed the mesh cabinet!
The transmitter uses one tube (a 6L6) and puts out about 10 watts on the 80 and 40 meter ham bands.
The workmanship is beautiful inside and out.
I can't imagine how many hours were spent creating this little gem, but I greatly admire the person who has this kind of skill and patience!
