Strange indeed. The only explanation I can think of is that some major part - maybe the whole chassis - was replaced at some point. Martin

Sidste chance ! Hent dem for DKK 500.- Martin

Thanks also to you, Paul. Yes, I checked the datasheet for the transistor and I was aware of the diode but not the resistor. I tested the transistor out of circuit and was fooled into believing it was dead, but it's not. Obviously a very low impedance B-E path is needed. I couldn't find any obvious faults, the C101/102/103 etc. all tested fine

Yep, 25 ohms DC resistance both ways between B-E so definitely dead. I just wonder why. When B-E shorts occur there's usually a good reason but of course the reason here could be the transistor itself. The built-in damper diode sits between C-E if I'm not mistaken. I'm aware of it, thanks. Martin

The Beo4 won't operate the Beomaster 5000. Martin

Thanks guys. Tournedos' MX6000 case thread and Die_Bogeners wonderful MX workshop thread are both superb sources of information. I measured around a bit and found a B-E short on TR33. C100 and D82 both seems fine though I will of course replace C100 while in there. I suppose a C-E short would potentially have damaged the HV transformer but a B-E

Thanks, Neil. I see where you are going but I don't have a Beo4, can I use a Beolink 1000 ? Martin

Geoff, Very interesting though I am a bit sceptic regarding the serial number. They are normally somewhere around the 1610000-1620000 range for the Beolit 707's and B&O only used the serial number 1 once, and that was back in 1925 or so. A photo of the number would be great to see if possible. Martin

I agree that the broken PCB should be investigated. The problem sounds like the typical too high idle currents so that would be a thing to check. Martin

I have a Beovision MX6000 currently on the bench. I normally don't do TV's or VCR's so my experience in these matters is quite limited. This particular white design MX6000 is in mint condition and one I really would like to get going though as the plan is to put it into daily use. Problem is that it won't start properly; Mains on brings
