Focus was terrible, but it got better as time went by.

Can ya spot the SS device ? http://2x2l.com/nabcam_pg/index.htm Excellent pix! Thanks. Last year I rescued a meter panel and a few other parts from an early 1950s RCA TV transmitter; I was working at an an FM transmitter site and the TV engineers were tearing apart their long unused first TV transmitter. Thing was built like a battleship and it must have taken a full-time person to keep the thing tuned and in alignment. Now I have to ponder, one more time, what the heck and how in the world did RCA go down so quickly. They literally *were* TV for many years. Incredible. ..

I never tinkered with it, but I remember it was marked CBS and the guys who did use it were among the brighter guys in the club. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
