Shows the manufacturing and testing of RCA Color TVs including environmental and operational testing

RCA developed and held the patents to most of the circuitry for the NTSC color TV system. Thus every TV maker in the US and free world that used our NTSC system had to pay royalties on every color TV tube (CRT), deflection yoke, and about 75% of the circuitry used in their color TV's.
It wasn't until the mid 1960's when Sony developed their "Trinitron" color TV crt tube that a color TV appeared that didn't follow 100% exactly the RCA system of color reproduction. Thus Sony didn't have to pay the same amount of patent royalties to RCA as other companies.

HAMMARLUND SP-600 J-22

I am the proud owner of this Hammarlund SP-600 J-22 S/N# 14118 Shortwave receiver from 1953.

I have just re-tubed with nos Jan Tubes and re-capped this receiver.

This unit is in good shape, very clean and sensitivity is very good. the faceplate could use a new paint job but right now I am more concerned about it's operation.

TRIPLETT 3413A

  This is my Triplett 3413A tube tester that I have fully restored to spec, and I love it.

a great tester because it covers a lot of tubes from old 4 pin, octal to newer types. it is also pretty darn accurate for a less expensive tester. let's face it it's not a Hickok.
