Hi Mark,
The set appears to of late '60s production, the electrolytic capacitor in the attached picture is dated 6742, 42nd week of 1967.
Transistor TR1 is a Mullard BF194 and has the code D39 on it. Tr3 is a Mullard BF194b and has the code 0g3. I'm not sure if these codes are the date manufacture or for other purposes.

DFWB.
