Thanks. Allan
For me i have put the screws back in with the rubber gourmets also and it did help a lot
Can you touch the tone arm with the TT running (plater turning )and feel the vibration coming from it? i sure could and can still today
i have a new motor they sent me still i just may have someone put it in for me the Dealer told me they would do it but i am not sure if i trust them any more and they all know me at the store by my first name i have been going their for over 20 years and have brought many things their i was the first one to buy the 2 new NAD amps 2600 and the 7600 bridged together witch has 3 K of power LoL a lot of power.
i still have them but now use the ones from NAD the silver series S-100 witch are 250 watts/channel i have two of them one for each channel set up as mono

because of the SDA speakers and they need a common ground
