🙁 There is a fuse. Open it up and take a look to see if anything else has been cooked.

Thank you peter . Will do so when I get back home next week from the work trip .

In case it’s the transformer , do you know where can I buy this part to replace or which models of Beogram share the same transformer with bg 5500 ? 

Regards

peter

The parts in the BG5005, 5500, 3000, 3300, 3500, 4500, 6500, 7000, 8500, 9000 are largely interchangeable. People part these out on eBay, you can email Beoparts.com, I might have one in storage, there are Facebook trading groups for B&O. If you’re a gold or silver member here, you could post a wanted add.

You’ve got options if you are partly capable of repairs yourself.

You might even be able to convert it to a 220v transformer and save your lady some trouble and guilt in the future.

Power supplies are not identical in RIAA and non-RIAA decks.
But how much has burned? Fuse, rectifier, transformer, something on the main board?

Hi guys ,

opened up the beogram 5500 with no sign of life .

the fuse is not burnt and this cause me nervous .

i am not a professional technician but only have secondary school student  electronic techniques .

i have carefully  disconnected the power supply part and will start to check .first the transformer , then will try replace the voltage regulator. Wish me luck .

Hi Peter ,

After founding the fuse is without damage , i did check up the transformer , 120v input on the primary side but 0v output from the secondary winding . 

Does it mean I need to find a new transformer ? Sorry for my ignorance . It is 30 years ago I put my fingers on a multimeter !

i found some replacement at eBay which are from Rx , 1800 or 5000 , outlook are identical but numbers printers on it are varied  . Mine is 8013274 , are they all the same ?

and some smaller pcb are 240veuro version ?

which one I should go for ? Please help and advise .

regards

david

Hi Martin. 

Fuse is not burnt . transformer checked , 120v input but 0 volt out . Think I need to buy a replacement transformer at eBay . Will also change the voltage regulator ic too . Think these are the vulnerable parts of the power supply side , right ? 

If I buy the 240v eu version transformer , the pcb seems different . Anything I need to concern ? Please advise .

regards
