I got my tweaked Walker CJ55 record deck running again today with Rega arm and cartridge fitted amongst many other mods.
Subchassis has two 32 mm brass door stops bolted into recesses each side of main bearing to provide mass damping. These are hollow so I wanted to fill them with lead shot, or maybe ball bearings, but can’t find any at the moment. The sub chassis has also been reworked and refined with more filling, sanding and a respray in satin black.
The wood spring hangers have self adhesive cork strip on the underside and the MDF arm board has plaster of Paris set into circular recesses on the underside.
The two conical springs at the arm end of the chassis are packed up with rubber isolators l scavenged from a dumped fridge unit in my back alley (super womble
Finally after cutting a 23-24mm hole in the arm board 222mm from the centre spindle l fitted my RB300 arm. The arm pivot was too low at first so lacking any arm shims (Rega arms are not height adjustable without Rega shims, or you have to make some), l packed the arm board up on its mounts with triple stacked 38mm repair washers.
The results on audition were surprisingly good. Much more depth, resolution and out of the box sound. Ok so now the speed stability or lack of it became more apparent to my ears, but it was fine with Hawkwinds ‘All aboard the Skylark’ as l had hoped.
Makes a change from sawing and sanding wood and filler all day!
