Rick,
I built the 3A and still have it. I probably ought to go through it
again. Who knows what shape some of those caps are? One of those things
in the garage I have trouble removing.

Yes, we owe a lot to Bell labs.
In 1958 I built my first crystal set, and in 1959 I added a single
transistor audio amp to it.
A few days later a 59+ 200dB signal blew the headphones off my head.
It was a ham who lived about 100' away from me. He was working AM of
course.
I had never heard of ham radio before.
I removed the antenna, disabled the amp and copied him on the crystal set.
Eventually he said his address, so I looked him up and got bitten myself...
I remember the guy's name but not his call sign.
He held my hand as I built my Heathkit AR3 receiver.
Then I "borrowed" a cake pan from my mom's kitchen and built a 1-tube CW
transmitter inside of it.
I taught myself Morse code and was soon pounding brass.

Rick,
Even dating myself more, I worked at Bell Telephone Laboratories in 1953 to
1956(with a time-out for the Signal Corps). Had the fun of designing a
circuit using a point-contact transistor then managing to blow up the first
junction one in our lab by putting a lantern battery power supply across the
base-emitter diode in the wrong direction.
Lots of water under the bridge, but still enjoy CW and wanted to encourage
James to take a deep breath and jump into the pool.
