My CDX is faultless again. It might have been the cd but it plays well.10 days on standby was all.
Anyway how long will it last? Depends on the repair. With age on B&O being 15-20 years before something needs service. A Beocord is a good example. What is typically wrong is the belts have melted or snapped. The 250 fuse is not aviable every where but can be found. Nothing else really as the electronic is yet too prove faulty in most of the units before 1986 exept the LED lights. A B&O dealer can't repair that either.
Pre 1986 is where it's important to at least try before you buy if you can. This goes for audio and video.
Let's take my CDX again. It had the natural age trouble with the left hinge broken and some electronic repairs. The hinge is not a sparepart. A fellow Beoworld member had a solution which is posted in another place here. Dillen did the rest and it works great. If done correctly the age faults will most likely take a decade or two before having trouble again. Replace a cap will last just as long if it's 100% correct and the soldering is right. Soldering is very important. It can cause many faults in units.
Earlier this year I went on the hunt for a Beomaster 8000 and 4-5 offers were aviable. The first one was at the Lauritz.com auction and since it was nearby I went to have a look. It was dirty, smelling and with power on (no speakers aviable) stuck in one place electronic wise. Clearly a repair mans delight?
The 3rd one was a nice working one but the price was naturally higher. The selller collected offers and got sold to someone else without seller contacting me for a higher bid. Now a working unit is great but a complicated B&O unit is more of a repairs and who did if any and when? It does come up at some point if you don't have answers to these questions.
The second one was for sale in february. Ruins fuses! A CDX with faults came with it. As I knew Dillen he got it to fix. It was full of former atempts of trying to do qualified service and loose connections. With all faults done and a new net transformer it was cured and plays wonderfully today.
Speakers mostly have foamrot. S80 and S120 may look good on the outsite in an ad and person when picked up but be prepared to have something fixed. I got a pair of each this month in white with stands but foamrot. When done they will last another 15 years at least.
Been unlucky here? Pre 1986 B&O is more hit and miss in the B&O world. I don't care if it works that much as long as they look good on the outside and most of it does, the bottom line is it can mostly be fixed. Be it Beograms, Beomasters, Beocords and so on. Just have a good repair man on hand.
