    while you are in there i would clean the micro switches with contact spray as these oxidise and fail

    Hello again. I don't seem to find the right way to place the protective caps back again. I introduce them on the contacts but they stay lose and if I invert the mechanism upside down, they will fall off. Now they are not firm as they were before removing them. Are they originaly glued, or what....?
    Kind regards.

    Unfortunatelly, until now, I don't find how to clip them back again. I've tried and tried.......but nothing.

    In fact (if we're talking about a RX-DT505 or similar) once you take out the cassettes mechanism out of the whole unit, it is not complicated at all. As I said, not even those two "stubborn" connectors are really needed to be released. The only thing you really must do is desoldering the cables off both motors. Then you are able to "open the board" and easily gain access to the wheels where the belts should be placed. (There are two other little connectors which are very easy to release as well as a couple of screws.)

    Hello again...... Can anybody here help me with some information ("name" and size for example) about the screws I circle in the picture below? As you can see, they are the ones that fix the head mechanism. I am in the need of finding at least four of them.
    For any help, thanks in advance.

    There are very small protruding black plastic "pins" that snap off easily. Very easily. Then the clear plastic cover will not hold in place anymore. Held with little snap on plastic pins. Look carefully you should be able to see what I mean. Epoxy back on. But make sure to do it correctly!

    Overall very similar to the Panasonic RX-DT707 which I recently covered in the thread

    Probably 2.5mm to 3mm and they were originally JIS Philips screws. Easy to strip. About 10mm length. I would send for a metric pack assortment on e-bay to test fit which ones work.

    Don't forget to post final pictures of the Panasonic RX-DT505 when it is all done and, most important, what you think of the sound. "Freaking Amazing!!!" is my impression of the RX-DT707 at least :biggrin: :thumbsup:

    You said it all. It's also "freaking amazing" how the RX-DT505 sounds (and records) for this category. And I must add that they (505, 707) are evrything but easy to find in Germany. Kind regards.

    This is the first one that I bought some months ago, and which made me want to have a second one. That second one is the one that still is under repair (not in the pictures). Not too much time and several other things in which I must invest that very time.​
