The photo shows one of the many detailed sketches in our 6V6 tube transmitter kit. The kit manual covers the usual assembly, wire point to point connections, etc. In addition, it shows the wood chassis construction, the coil winding procudure, wound on an 8 penny nail jig (yes! the nails are in the kit!) This kit also tells what kind of tool to use to drill the screws, AND a suggestion where to buy the tool! We have sold many of these kits, and not one disappointed customer.  Speaking of selling, we just finished selling our products on eBay. Great response! We are almost sold out, and are busy boxing up additional kits...These will be shown at the upcoming Findlay Ohio hamfset - email for our newsletter for more info -  73 ES BCNU! GLENN NN8G
