552 burndy cable stuck

When you say stuck, have you managed to undo the locking collar or can you not get this undone. If this is the case, pushing the plug gently towards the socket should be enough to allow you to unlock the collar and then withdraw the plug ?

whatever i do i am not able to unlock it... 

the unlock is counter clock wise right?

Yes, anti-clockwise. Unlike other components, these can be very tight for some reason on the 552. I cannot get mine to lock, so if yours were locked it may take a lot of effort to unscrew the locking ring. 

Looking down, assuming you are in front of the unit, although it is "counter clock wise" to undo the locking collar, it would appear as if you are turning "clockwise" to undo ........... if that makes sense!

You are not alone...

I think you need to get yourself a strap wrench per the discussion in the above thread. Reminds me mine were tight last time, need to source a strap wrench.

towards the short end of the ps to unlock right? 

If you are looking from the back of the the PS, "counter clock" would be away from the short end.

If you are leaning over the unit from the front, looking down, the movement to undo the locking collar would appear as if "clockwise".

Try doing it with a pair of marigolds (rubber washing up gloves) on your hands - it might provide more grip. 

i tried tried....  this is industrial design at its best...i am about to hammer it 

Now you sound like my father in law (Bob a Job). He's hammer happy!

I'm not a fan of this method.

i got it with a delicate hammering!

now listening for the first time my preloved cd555!! wooowwwwww never heard Biko like this..... this is far better than cd2x! 

I can’t help thinking of the old adage “if the only tool is a hammer everthing becomes a nail”.

The right tool for the job is a strap wrench.

OK everyone . . . take out your hammers and confirm that tapping the Burndies provides a noticeable improvement!  (It's Friday...here comes the weekend....)  

In my previous life I had products that used Burndy & similar locking ring connectors.  After a few years in oceanic atmosphere,  stuck rings were common.   We had a tool that used a fabric strap to grip the ring.  We made them ourselves,  but the principle was based on an oil filter can remover.  (see pic)     Obviously not a made to fit solution for you,  but maybe a screwdriver & a length of cord (shoelace or heavy string) wrapped around the locking ring could work. 

it is like diamond cutting sort of hammering dont worry, it is hard to find exotic tools on a Friday in Saudi

When other methods fail, percussive easement will ensure results. I accept this may leave equipment in a less than optimal condition.
