Yeah, that would definitely work. Except that the people who have the
most problems with jack failures are ones who, like myself, are
constantly plugging and unplugging the headphones, for whatever

What about just keeping a mini extension plugged in to save the jack from
future wear?

I don't know about the K1 but if you are going to replace the jack in
your K2 you might consider wiring a separate headphone/speaker switch
when you do so.

Yes, the same thing applies. The little plastic lever inside the jack

I did it a couple of years ago with a standard 25w soldering iron no

Fortunately it is pretty easy to get to the K2 headphone jack if you want

The problem with the headphone jack on the K2 is not a new problem; you
cannot expect it to last forever. My solution was to take the audio out of

Another way to treat that jack more gently is to use a right-angle adapter.
That greatly shortens the "level arm" sticking out in front of the K2.
Can't say it's the reason, buy my 11 year old K2 still has the original jack
even though I use phones 100% of the time (and a right-angle adapter).

John,
If you have no de-soldering tools, try to get the solder out with wick,
but if that fails, cut the jack apart and remove the pins one at a time.
I don't see any advantage to not using the headphone jack. Who knows,
the new one may last forever.

Thanks much

I use the line output for my computer, including sound

I use the rear panel speaker out for my headphones or

Before you do, I suggest that you carefully check to see if it conforms to

The normal headphone jack failure leaves the speaker dead, but the

It is possible that the switch in your headphone jack failed so that the

The headphone jack seems like a proven part. However, from what I

the jack that has the most failures. I know mine on 6233 has been
