I have worked on RCA 3-RF-91 Models before which
are covered by the same SAMS Photofact except
with plastic cabinet. I didn't check for differences
other than the 6-RF-9 having a wood cabinet. This
radio has Chassis RC1129A. These models play
extremely well. Owner very pleased.
Now look at that chassis and the way it was
inserted at the factory...the sealing around the
speaker. The dial pointer came from a Zenith radio.
This radio came from a home of heavy smokers. It's
incredible the build-up of smoke crud. I just did a
cleaning to remove the heavy stuff because I had to
handle it. Sticky stinking smelling radio.
