Did anyone build their first B&W TV Set?
I did, sometime in the mid 1940's, while I was still working
for WMCA Radio.
It was a 10 Inch Round CRT Transvision Kit that I bought from Perry Brumfield of CBS.
It had a 13 channel Turret Tuner and came with a wooden cabinet.
It was patterned after the old RCA 630. It worked fine without any alignment.
I sold it when I graduated to a 17 Inch Zenith.
