Earl,
The SX 130 had a one piece cabinet, not a flat top cover like the
SX 122. It never came with a back cover. The tubes should be easy to
obtain. You might try Antique Electronic Supply in Ariz. (They have a
website). If you are handy in the metal shop and have the metal bending
tools, you might try to fashion a cabinet and attach some rubber feet.
Every so often a parts unit comes up on the online auction site.
The SX 130 is a nice mid price range receiver for short wave
listening and can receive AM, CW, and SSB broadcasts. Mike KF6KXG
