Must be referring to some light synthetic oil. Sewing machine oil, gun oil, even Mobil1 5-30 or Slick50 could be OK.

I've also got "Herb Albert's Tijuana Brass Whipped Cream and Other Delights". Better recording, although the horns are in the distance now. The stage has really moody reverberant qualities.

The load impedance of the Goldring eroica cart is 100R. Does that mean that R2 in the RIAA schematic should be 100R? - Yea I am the proud owner of a new deck

The Rock? Congrats. The input resistor across JFET gate to ground is the load resistor of the stage that the cartridge is connected to.

I notice dust is building up on the end of the cart. Not sure what to do about this. I had the idea of tying a string between the spindle and tonearm rest, to hold a piece of toilet paper against the record. But this will not prevent dust exhumed by the needle from sticking to the cart, and it may cause static and other problems. Unless perhaps it was a dryer sheet. Hmm.

There used to be some little grounded cleaning arms with carbon brush end. Those were to be seated somewhere on the plinth wiping the record constantly as it was playing. Don't know if they are making them still if you will look for.

Myself, I'd clean the end of the cart with a soft artist's brush. To prevent, or at least slow down recurrence, I think you'd be much better off going with Salas's suggestion.

Toilet paper is problematic in two ways. First, it's abrasive - the fibres are hard enough to wear away vinyl, and second, it's a source of dust - as it wears away it will contribute to the problem.

How about craft pipe cleaners? They are made of cotton or polyester.
