I am new at this, so bear with me. my phase linear turtable was stolen from me 15 years ago, found it in a pawn shop last week, i could tell it was mine because it had my old ortofon mc20 cartridge in it. anyway, i need the tone arm counterweights to make it maybe work again, not sure if i will ever find the pre pre again for the orotofon, but one thing at a time!! any help would be great. :lol:

one idea is to just get a replacement machined,it just seems to be a simple circular steel counterweight,try with a square bit of metal with a hole drilled through first to get an idea of the amount of mass you'd need, then guessimate the size and get a hole tapped from the outside to centre then get hold of a plastic screw and round the end off so it fits in the thread of the tonearm, wont be ideal but it should work pretty well

i got a new counterweight done for my mitsubishi deck in an engineering place for £40, so it should be even less for a circular one.

or alternativly i know a good home you can send it to :)

The counterweight is 100g. I can measure mine and let you know.

Actually it came with two counterweights, a normal thin one and a fatter one for heavier cartridges. I am looking for a thin one.

I know eBay seller professor-bizzt makes a custom counterweight for the PL-L1000 and and Phase Linear. Sorry your TT got stolen but glad to hear you got it back. It's a great TT well worth restoring.

Rude-and-crude while you search for the elegant solution: Fender-washers glued with epoxy. They come at many thickensses so you can mix to get to the correct weight. If the center hole is too small, drill it out to about 2mm larger in diameter. Use a minimum of three washers, the center of which should be drilled bit larger than the outer two. Insert an O-ring into this area that is slightly smaller than the shaft on the arm (i.d.), and slightly larger than the drilling (o.d.). This will be your centering/friction-point so you can adjust the weight and also the resonance damper. If the thing gets thick enough to wobble, use two O-rings or more as needed. Source the O-rings at any industrial supply house if your local big-box does not have them in their flat-pull-out-boxes aisle.

Been there, done that. Ultimately, I found a bit of solid brass rod that I machined and tapped for the weight I needed. But the fender-washers were a reasonable stand-in until I found the pretty solution.

Let me hunt around a bit - I may have that (mains-powered) head-amp sitting about somewhere. e-mail me off-forum. No worries that it could be yours - I have owned it since 1978.
