Notes

Model M5D is the 2nd generation of a all transistor mains powered mantel radio produced by Astor. Has a similar case to the earlier model M4C, but with a updated front & simplified tuning. The M5D was a mainstay throughout the 1960's & was replaced by the 3rd generation all silicon transistor model M6D in 1968.

Transistors are Anodeon brand, Astor's own manufacture under license from US maker.
