I am putting together parts to build an O2 amp and I found that one of the parts is already obsolete.  The power jack (Kobiconn #163-7620-E) is no longer made.  I searched around and found no one else has ever mentioned this before which makes me think I am probably just too inexperienced with builds to find an easy solution, but thought I would ask.  There is a possible replacement (Kobiconn #163-7620E-E), but that won't be shipping untill June 6th or so.
 
The point: Does anyone know of a 2.1mm pcb mounted power jack that will be able to replace Kobiconn #163-7620-E in an O2 build, preferably one that is in stock at Mouser?
 
Thanks.
 
Edit:  I got a PM recently asking about how I got a power jack.  I had to get one from JDS labs because at that time (around April) the replacement power jack was still a couple months out, I think it was supposed to ship around July and I didn't want to wait.  I think you can use Mouser part "163-7620E-E" as the replacement for this part.  This info is from JDS labs, so I assume it is what they are using right now.

I started adding parts for the O2 amp to my Mouser cart yesterday, and ran into the same problem.
 
If you don't mind a 2.5mm jack, there is part #163-7625-E. It would need a matching AC-to-AC wall transformer. I am in the process of trying to find one.
 
One a related note, it looks like several other parts are backordered. I replaced the 12V regulator listed in the BOM (#863-MC7812ACTG) with part# 512-LM7812CT, but the potentiometer is backordered too (#688-RK09712200MC). Have you found a replacement for the pot?

I was actually able to find a 2.1mm power jack.  JDS Labs helped me out with that.  After that I placed my Mouser order and ran into the batter connectors and pot being back ordered.  It was such a pain to find the right power jack that I just ordered all the parts and the backordered stuff will come when it comes.  I asked the guy who designed the amp about the power jack problem and he is looking into solutions for it as well.
 
I am assuming that I can at least run the amp plugged in until the battery connectors arrive?  Or are they needed to complete the power circuit?

the amp will work fine without batteries (or battery clips)

Thanks for the tip about JDS. I sent them a message.
 
Looking at the board, you should be able to run the amp without the battery connectors as long as the wall adapter can provide enough current.

DS:  Sweet.  Thanks!
 
The wait for the pot isn't too bad.  I don't have a problem waiting for July to run it off of batteries.

I ran into the same problem... sooooo....
 
There is also this option...
 
CUI PJ-002A
 
...which can be found at Digi-Key. I had to cut the leads a bit to fit it on the board. It works fine.
 
Cost me $2 or $3 extra. D'oh! Didn't want to wait til June.

Anyone know some places that sell front panels?  I don't really want the JDS labs front, and getting one made at front panel express is a little much.  I heard there were bamboo front panels and clear plastic front panels out there.  Where can I get those?

This guy aerohoff on the diy audio forums sells the Acryllic and bamboo panels. Here's a link to his forum topic

You can see pics of the bamboo ones on page 6.

This is awesome.  I registered and sent the guy a PM.  Hopefully he isn't too busy to get back to me!
 
Thanks very much.
