Ah, bummer. I thought that the two 1:5 transformers specified in the patent might be realized with this part for an amplifier for use at 10 MHz only:
However, I got the feeling that autotransformer L1 might need some odd turns ratio to get the impedance matching right.
Am I anywhere close to making sense, or am I still droolingly clueless? :)

I didn't find them at Digi-Key, but I just looked at Mouser and found them still available, made by Central Semiconductor:
I'm so accustomed to tiny surface-mount stuff in my day job, that I'm always surprised to find anything through-hole still in production!
