Just bought a N.O.S. Korg PX4B!
 

Really excited to get my hands on this after doing a lot of research and reading, both here on TB and also other places around the interwebs. The fact that MarloweDK has used a PX4 for recording about a million great vids certainly was a selling point as well.

Wondering if any other PX4B users would be willing to share some info with a new user as to what to look out for, correct AC adaptor model number, what headphones you are using (the Sony MDR-7506 model is looking pretty good for the price right now), etc. I am going to use it with GarageBand and/or iMovie to make some vids for youtube posting and also recording to share musical ideas with friend s living overseas and such. Any and all info is greatly appreciated!

Adapter is KA193

I'm using Bose OE2 headphones.

Hi There,
That's a great unit. I have one myself. It doesn't get nearly enough use. I think I'm using the same Sony headphones you mentioned and I see you are getting the AC adapter. Good call! It chows on batteries. Really the only bad thing about it. Enjoy!
Take Care,
Brent
