Great news! The FB40 "rev B" kits are still in stock These kits look outstanding, with a new_and_improved PCB that contains:
no jumpers or part mods
circuit traces for a popular 1.5W rf power amplifier (from the Ugly Weekender" project of W7ZOI, published in Aug '81 QST)
circuit traces for a Transmit-Receive circuit to allow connection of a receiver to the same antenna as the FB40 transmitter
You can take a look at the revised rev B schematic or at the entire rev B manual (also revised) if you have an Adobe PDF reader installed on your system. (You can also download these to your own system by right-clicking on the links and use "save as" menu item.)
Here's a full-sized photo of a fully-populated FB40b and optional power amp.
Here's a look at the layout for a fully-populated board.
