  • Re: Refoaming Beovox CX50 and CX100

    Last night I started glueing the outer edge, using Craig's method (see earlier posts). The battery pulled the cone in perfectly and after applying the pegs, the cone seemed to be well centered. I first glued it in two spots (12 and 3 o'clock) and later in the evening in the remaining two spots. The glue sets in about two hours. Tonight I'm

    [quote user="Craig"] When I have done this I raid the kitchen for a suitable size cup or something that fits the inside of the ring perfectly. Then left some weight on the top of it, until the glue sets [/quote] Good idea. But the glue I use tacks fairly quickly and the advantage with my method is that I can tidy up excessive glue before it

    I didn't find the glue that I had originally intended to use. But after some research I found another that might even be better. It's called Casco Marin & Teknik in the nordic countries. I don't know what it is called elsewhere. It's avaiable in both white and black. Naturally, I chose the black version. I have now glued the foam

    [quote user="Marcus"]If the fifth band is purple that means that the tolerance for the resistor is +-0.1%. [/quote] WOW, you're right. I wonder why they used them and if the low tolerance is neccessary. Even more strange are the three resistors below the burnt ones that seem to have TWO gold bands. That's not covered by my resistor

    [quote user="Die_Bogener"] The cheapest coal resistor is good enough... 5% 0,25W. [/quote] What type are the original resistors, by the way? They have five bands: brown-black-black-gold-purple. I have never seen a resistor with a purple band for tolerance. Does in mean 0.7%? It can hardly be 7%, as it has four bands for resistance value, whereas

    Thanks for the tip about the batteriy Craig! I had intended to do as you describe, except for the battery. Now I'll try the battery trick too. Om monday I will buy a fresh bottle of glue. Then the work can begin.

    OK, I suppose this is one of the exceptions then. Elfa has the BC368, which might work (NPN, Ic-max 1 A). A suitable PNP transistor could be the BC640, which Elfa also stocks.

    I replace basically any small signal transistor with BC550C/BC560C. As long as it looks the same, it will usually work. There are exeptions of course, but they are few. You need to make sure it's a NPN or PNP transistor of course. FETs are another thing. For resistors I always use 0,6 W metal film. That way I only need to stock one type and can

    Those 10 ohm resistors definitely look fried. Time for a trip to Elfa...

    I received my CX100 today, and had a look at the crossover: The bottom woofer is connected in series with a a coil, as expected. The top woofer however, is connected in series with this coil and another coil that is paralleled with a capacitor. A weird thing about this second coil is that it has an iron core, just like a transformer. I thought this
