    Default naked tt2

    This is the noisier tt2
    It has the O ring idler from audiosilente in Italy

    Verdict here too that the idler is the culprit
    Convincingly louder than on tt1. There is even a repetitive 'grinding' sort of sound with each turn of the idler.

    I whipped of the idler and tried the 2 old original idlers from these decks - they were even worse.

    Default 'idler' as source of noise

    Both idlers are quite new
    The idler in tt1 i think i got from a fella in the US called mirko djordjevic
    The O ring idler in tt2 is from eBayer Audiosilente
    So both of the idlers or the idler assemblies are 'noisy'

    The diagram below details the idler assembly
    I got that from http://www.theanalogdept.com/td124_notes.htm with this note:

    Don't forget that little thrust washer at the bottom of the idler wheel. It is too easily ignored. Noisy idler? make sure its there

    Both of mine were assembled without any washers !
    I think this is the key - metal rubbing on metal - not good.
    I feel the more important one is the 'white nylon washer' and there should probably be at least one fibre washer below that and the whole assembly adjusted to fit with the stepped pulley.

    My tts were refurbished by a pretty careful guy abt 2 years ago- he did good with both tts - both were stripped and serviced with motor rebuilds and tt1 was painted silver becos of bad oxidation - but he failed to do the idlers correctly.

    the other pic shows 3 fibre washers i got with the audiosilente O ring.

    This looks like the solution to my problem of rumble

    Don't waste your money with the Schopper kit - you've already hit on the importance of the washers and this does not add anything useful. I know, because I bought this kit.

    Thank you Hugo, you just saved me 112 swiss francs. ( 2 x kit + shipping)
    Much appreciated. I ll be on the lookout for a nice smooth nylon washer or 2

    Hi Shahrin.

    I had my TD124 fully refurbished by Schopper in 2010 and I must admit they did a superb job and worth the money IMO but as said by Hugo, the idler washer thing isn't a good buy on it's own.

    If you haven't already, you should fit the Audiosilente main bearing gasket. This is another great upgrade. Another great recommendation from Hugo.

    Glad your sorted.

    For anyone else having ear to chassis problems a cheap solution is such as this :-

    when my 124s were refurbished i gathered a whole bunch of parts from various sources.
    Mirko D supplied many parts. He makes a variety of excellent parts and has put his wares on eBay but he can be pain to deal with.
    from father's illness to divorce(s) he takes forever
    I thiink the bearings bits were from him and they looked real good. Motor service kit too.
    I was looking at the idler from Mirko when i too the platter off tt1 - its very well made and resembles the original.
    hmm must have a look around in the old packages - see if there s a nylon washer or two that failed to find right home.

    Good idea Mark !

    It turns out that the nylon washer was there !.
    This is probably the original - a very thin nylatron type.
    I missed it when i removed the idler wheel, but my pal Lee confirmed it was there all along.
    So he adjusted the stepped pulley and idler assemblies.
    (The bushes were fine in his opinion)

    What then was identified as the next major source of noise was the main platter bearing.
    Turned out that there were flat spots on this 6 mm bearing.
    It has been replaced.
    btw the thrust plate was replaced about 2 yrs ago by part brob from this Mirko guy in the US.
    Further mods included replacing the 4 threaded rods by longer ones so the chassis is now secured by 4 bolts at the bottom of the plinth.

    There are other mods to the armboard as i have switched back to the thick original Swiss wooden armboard (from a crappy L shaped one).
    Its much quieter when knocked - but i will discuss that an another thread i started about mods to the 3012, headshell etc to update the rm and optimise to the 103R.

    I am really happy that the noise level is much reduced now to a level I can live with.

    as mine were ossified being 50 yrs old.
    Look at the pic and u will see that this guy meerp1 also makes a brand new slightly thicker top platter for the 124
    He has put that up on eBay before. Looks very nice.

    Yes I need some new pads for my TD124. I have been using a silicon gel tape, made out of the same stuff used in the motor vibration dampers. But because the tape has a slightly rough edge when cut into little pads it tends to get pealed off the plater.
