Life & Death of the Plug_Jack P110/GP300/GP350 & Others

<b>Hi:

Probably will get into trouble here, but
many inquires have prompted the issue.

1. The External Mike Cords are made in China
and are made up of 20+ strands of .002 dia copper wire enclosed in a cheap poly-
vinyl coating

When persons make accessory items, soldering
to these small wires ( even twisted ) can
break very easy. Hence the importance of a
interface box when/if external devices are
used.

2. The External Jack is another focal point
of problems. Many times if debris enters in
the Jack Housing it can contaminate the sensitive contacts, and cause deteriorations
of the small ( white ) spongy supports. These
supports loose their capacity to allow the contacts to apply pressure on the supports, and they too deteriorate over a period of time even if not used often.

3. Also, the External Mic wires " Break " inside where the Cable supports are located
both at the plug, and Jack/

4. Exposing the Cables to Extream Cold or Heat will accelerate the process

IT IS VERY important that when the external
jack is not in use, the rubber cap be firmly
in place. If it has been removed, get a replacement

To replace these components from a component
price stand-point is cheap, the labor on the
other hand is a different ( and can be ) expensive issue.</b>

Yes.. we had all those problems too, thankfully we sold up customers to HT1000's whenever we could.
But on quite a number we removed the mic jack completely when the board traces finally gave up. Then we cut the mic jack off and wired the speaker/mic right onto the board and that cured the problem, but permanent speaker/mic though
