BANG & OLUFSAN STEREO !

Hi there all I have a retro B&O system comprising of Tape deck - - Beocord 2400- 1 button loose can be glued back does not stop functionality -- Din connector could not be found. BeoMaster 2400-2 Tuner/Amplifier does not power up I have changed the fuse - not the internal ones as they look fine ?? so enthusiasts only as it is not working at the moment but I,m sure someone can get it going - Note this amp is not a phono input its Din plug --Remote control is missing for B&O Phono - Beogram 2402 - this works has a strange way of starting /stopping record has attached lead B&O is worth a fair few quid when all working If i could get the Amp running i would be asking 250 the price tag is due to my lack of fixing amps knowledge Also Kenwood Amp/ Receiver KRV7050 -- will not turn on past the protect sequence may have has some damp close by as small amount of rust on bottom metal panel And lastly a CD player made by fusion which is a Cambridge audio in disguise -- works fine and till I find it remote is missing from the fusion cd
