[Hallicrafters] SR-2000/P-2000 Tick when HV is applied

[Jim Liles]

Good evening:

We posted a note on the Hallicrafters reflector some time ago regarding a tick when the high voltage is applied with the SR-2000 - P2000.  We successfully cleared the problem by cleaning the P-2000 connector.  Since then it has reappeared.  We now have a definite fix.  Both the P-2000 and SR-2000 connectors have a metal jacket.  The P-2000 connector has a plastic insert that is held in place by a screw.  The screw, when inserted, contacts the metal jacket and apparently is too close to the 2700 volt pin.  This causes a static voltage to build on the jacket that finally arcs to the jacket in the SR-2000 causing a tick and noise of varying duration.  The fix is simply to replace the metal screw with a nylon version.  The absence of the tick and reduced noise level is worth the five minute change.  Kindest regards Jim K9AXN
