I didn't know that Heathkit did TR's in the UK Derrick
Interesting! Can only find USA models AD 16/22/and 72. There is a Heathkit STR1 Daystrom model from the UK [1968] which seems to have a black [joystick] BSR type deck but not [I think] the absolute basic one used in many cheaper UK TR's!
Any more ID on this at all?
