Well, the short answers are no and no. The only way is to find a working driver from a donor Beovox P45. These woofers fail at an alarming rate, especially in transport and when moving. Magnets are glued on, the glue losens, the magnet dislocate and the coil becomes stuck. Result is a completely frozen cone, producing no sound. All P45 owners should

Yes, those are indeed TO3's. B&O have used RCA transistors in the 1960's (Beolab 5000 springs to mind) but I never came across that type before. My guess is that they were mounted as being the best option by a previous repairer. If you can make 2N3055 work with regards to temp. stability and idle current, which shouldn't be too hard

Hej Kim og velkommen til Beoworld ! Det er en standard fejl på Beomaster 5000. Trimmerne til tomgangsstrøm bliver dårlige og må udskiftes og efter justeres. Skift een kanal ad gangen og begynd med den, der sidder i kanalen med den højeste tomgangsstrøm. Er dette sort snak for dig eller har du bare ikke mod på

Good job ! Martin

shhuang, you have a message in your inbox (upper right corner of the page) regarding belts. Martin

These types of capacitors have nothing in them that can leak out and they are normally incredibly reliable components. My guess is that it's something that was spilled down from above, next to the long black release bar. I suggest you desolder the two caps, clean the board if possible and mount them again. Martin

2N5034 is not a TO3. It's a TO219a if my memory serves me right. It's found in other Beomasters from the same years, Beomaster 1001 etc. It's pinout can look a bit like a TO3 but it's smaller and the housing is square rather than eliptical. I may be able to find some good used 2N5034 but are you sure that the chassis fitting is for a

1g sounds a bit low, even for a CL cartridge and you're right in assuming that the tracking force scale shouldn't be trusted 100% anylonger. Most original cartridges have hardened suspensions to different extents by now. Try increasing to 1.2g or even 1.4g if for nothing else than the diagnosis. If the cartridge is fine, it won't damage

Hej Mikael, Jeg har ikke den store forstand på de nyere produkter, men jeg går ud fra, at det ikke er et B&O produkt, du har fat i, da svaret ellers sandsynligvis ville kunne læses i brugsanvisning(en/erne). Måske det ville hjælpe hvis du fortalte hvilket fabrikat/model DVD afspiller, det drejer sig om ? Martin
