Bottom cover Martin

Et rigtigt værksted er et sted med folk, der kan reparere defekte ting så de kommer til at virke igen. B&O's værksteder kan for det meste kun udskifte moduler, de kan ikke reparere dem. Det vil med andre ord sige, at når modulet ikke længere kan bestilles hjem, er de hjælpeløse. Jeg har repareret mange

Actually, that schematic is practically all you need if you have a little basic experience with servicing valve sets. I am particularly fond of the valve pinout drawings at the bottom of the page. Expected voltage readings are printed here for selected valve pins which allows for a fairly quick diagnose of the most common faults. Very nice. You won't

Hey, the sheet with the schematics is still in there ! I will leave it there. I will work from the service manual anyways and the schematics may come in handy in 50 years when the next repairer will be servicing it. Martin

The plug-in module that sits right in front of the output stage with its ECC83 preamplifier valve works with the record player input and functions as an adapter for different types of pickup cartridges. The one currently fitted is for a Crystal type (high ohmic) cartridge. Glued to the inside of the cabinet is an envelope that originally held the schematics

The JET 606 is a fairly large set that typically saw use as the daily set in the livingroom of a middle-class home. It has provisions for connecting a record player and an external speaker. Being a Bang & Olufsen set of this nature, it will be a good performer and thanks to the PL84 output valve, it will provide a whopping 4,5 Watts output power

The model name JET suggests a position right in the middle of the model range, functionality-wise. Jet was a bigger and better build than a MINI but cheaper and not quite as technically advanced as a GRAND PRIX. Martin

The JET 606 was made for the 1960 season and was featured in the 1959/60 catalogues, actually the Moderne version took pride of place on the page. Martin

All knobs are present, and most of them seems to operate nicely. Actually only the dial knob does nothing. It won't rotate, but just sits there like it was glued to the chassis. This will have to be investigated. My guess is that the dial string has snapped and is now blocking the mech somehow. Still, I would imagine that a fault like that would
