  • Shanghai 452, a tube, radio is similar to model Shanghai 451 - see an article from ZTL here about it - and some transistor sets with the same number designation,上海 451. For Shanghai 452 there is a separate power unit to put underneath the set for line power - as shows the picture in the manual on page 88. Model 452 receives broadcast 550 - 1600 kHz and SW 6 - 18 MHz.
