    I also have the Marantz 6300 turntable witch need new feet this should be interesting, the particle board will make it challenging I would imagine ??

    Unfortunately, the plinth is solid, there is no access to the rear of the mounting holes, otherwise that would be a great idea, no impact would be ideal. Thanks for the idea scott944, I'll see if I can adapt it to the situation somehow, once all the parts are here.


    Your kit should've come with new vellum for the dial, and two meters. That vellum on the dial is easy to remove, but the glue takes forever to get all that off of some parts. You may get lucky and the old vellum pulls up with all the glue still attached, and not leave any behind. It won't harm your plastic face to remove the old vellum.

    I used 5mm double sided tape to put the new vellum back on there. Amazon links don't work on TGP, search this:

    The particle board should take the M6 tee nuts just fine, but I'm worried about hammering on the bottom of the plinth - I'll go really slowly at first. As long as those tee nuts go in straight and flush, the feet should be perfect. Those other feet I bought were non-adjustable and looked goofy being all crooked and clocked at different angles.

    I've put together a more comprehensive thread over at AK regarding the 6300 resto, this will include links to parts necessary for rebuild:

    How about pressing the T-nuts in ?? I hate hammering on delicate gear. Just the word Hammer sounds violent..

    Also the Velum I got with my kit is there it's just taking off the old.. Thanks, Robby..

    The old vellum comes right off, if you tear it so what, you're replacing it anyways. The plexi face plate is really strong - it's only the glue left behind that makes for time consuming effort. Rip it off there!

    For the T6 tee nuts, maybe I can use large C-clamps with felt on both jaws - to press them in, instead of hammer them in.

    It's a thin walnut veneer on top of the plinth, damaging that would be the worst thing I could do, IMO. I'll need to really spread out the pressure of the top jaw, a flat block of wood or the like up top should disperse the pressure on the veneer.

    There's no turning back now, this will have to be accomplished somehow. This could all turn out to be an expensive failure - stay tuned.

    Waiting for parts on the 2275 and 6300, it was time to open up the 5030b tape deck:

    I ordered the (3) belts for the drive mechanism, and an idler tire (pinch roller), hopefully those will be here soon. Will first rebuild the drive train, then recap this. Lot of caps on this one!

    Got the 5030b Cassette Deck belts:
    [​IMG]

    Old belts turned in to grease:
    [​IMG]

    Took forever to clean all of the belt surfaces:
    [​IMG]

    [​IMG]

    [​IMG]

    All clean, new belt going in:
    [​IMG]

    Only had to replace the two main belts, did not need to replace counter belt or idler tire - works great - correct speed and all functions:
    [​IMG]



    Back together and demagnetized:
    [​IMG]


    Re-capped the 6300 Turntable.

    New parts going in:
    [​IMG]

    Need to replace (10) of these switches, first one completed:
    [​IMG]

    Stock power supply board:
    [​IMG]

    New caps and done:
    [​IMG]

    [​IMG]

    8 out of 10 switches completed:
    [​IMG]

    Going to upgrade the tonearm wiring and replace the 1k pots, to do this I'll need to remove the tonearm from the plinth. Left the last two switches until that time comes:
    [​IMG]

    Old parts:
    [​IMG]

    Need to remove metal cover and tonearm to get to pitch pots will follow-up later:

    Too many pics, had to make a second post.

    Isonoe Turntable feet installation:
    [​IMG]

    Next to stock foot - perfect height for conversion:
    [​IMG]

    M6 tee-nut fitted and ready on new foot:
    [​IMG]

    Drill existing holes out progressively larger with 5 bits:
    [​IMG]

    Now the hard part - hammering them in the plinth:
    [​IMG]

    One done:
    [​IMG]

    Two down:
    [​IMG]

    And an early celebration of success on the wood tapped feet:
    [​IMG]

    I need to drill and tap this last metal brace, for the M6 screw on the last foot:

    Marantz EQ-20

    Looks like my EQ might be from this series. I’ve seen these particular units with the wood sides and without. I’ve considered selling it because my new old school receiver has an onboard EQ that works well. But damn it pairs well with a turntable. Also works wonders for 8-tracks.

    Marantz gear not only sounds and works great, it looks amazing too. Nice EQ!

    Finished the last foot on the TT, drilled and tapped:

    Mounted:

    Assembled:

    Looks way better than the other goofy feet that were non-height adjustable:

    Before ordering a new cartridge for this, I figured I would check out the alignment\position of the current cartridge.

    Got one of these to measure the alignment:
    [​IMG]

    And one of these to measure the tracking force, 2.0g is an ideal cartridge weight for this 6300:
    [​IMG]


    Thinking about replacing the current cartridge with an Audio Technica VM95ML:

    The current cartridge is a Pickering XV-15 1200E - with maybe 600 hours of use:
    [​IMG]

    This 6300 TT has maybe 6 hours of work on it in total.

    The Hakko 301 de-solder gun is the best piece of soldering gear I have ever used, it made this entire job too easy, in fact all of the Hakko tools made this job fun:

    That Pickering is a very good cartridge.. I would loose the brush as those tend to foul your stylus easily.. Moot point if your getting a new cartridge.. however, I’m excited to hear how you like the new feet!

    After doing some reading, the Pickering XV-15 is the same as the Stanton 681EEE - the D1200 styli, is also known as the 1200E that came with this XV-15 from the factory. This is a really good setup as it stands, apparently.

    But I have this extra headshell that I could use to test other options.

    If I can't get the tracking force and alignment right, I'll take off the brush, if I can make it all work, I'll leave it - it's like curb feelers on an old Caddy.

    You can't go wrong with anything they make, it would seem.

    With this 301, I'm already looking at what I can overhaul next.:eek:
