Vintage Blaupunkt Derby De Luxe Multiband Shortwave Radio AM/FM/SW/LW

Description

Tested using a 6V adaptor, requires 9V but did work.
Had a buzz on all bands, may have been the 6V supply.
Also operates on 6 "D" cell batteries, door held closed with a cable tie.
No batteries or power supply included.
The case is quite rough, also comes on immediately...I simply may not know where the switch is.
