Welcome to Beoworld !

Could be a shorted output. Have you tried with no speakers connected ?

Martin

hi thanks for the reply have done but the problem remains thanks..ken.

It could be one of several things then.
Most likely the output stage which, in your Beomaster, is one large (and fairly cheap) chip.
If this is indeed the case, the repair shouldn't be too costly.

Martin

looks like you may well be dead right with this one.anybody know of a supplier for the chip.regards ken.

I replaced one in a Beomaster 2000 recently (should be the same one).

Just search on eBay for "stk463" (or whatever type yours is). I replaced mine with a Stk465 that I paid 6€ for.

Can you replace it yourself ?

If the chip in your Beomaster is a STK 463, I have one.
Actually, the one I have is a STK 465 but that only means
you will get 5 Watts more per channel.

Edit: Oh yes, there are some available at Ebay. Make sure to get the correct physical outline.

Martin

thanks for that there is indeed one for sale on ebay ..regards..ken

update  got myself the the stk power amplifier and with a bit soldering i now have a restored system. Thanks for members  assistance.

Great stuff and worth a couple of hours work, glad it was such a straight forward fix
