I have a question: what does the B before the 5k means?

Linear.

A 4.7K one should do the job just as well.

Default P3000 pots

According to the schematic/partslist, the front panel pot for channel 1 of the P3000 is R24A/R24B, whcih is a dual 10K pot, not a 5K as you stated. The part number for the original pot (Hafler) is RV-0818; the mfg (ALPS) part number for this part is 344A-10KBx2.

Hope that helps.

B means linear taper. The value is not that important. Anything between 4.7K to 25K should be fine.

I am selling Hafler part number RV-0818 on ebay - search for it if you need one! It is the vol control for the P1500 and P3000.

I sure hope he hasn't waited these last eight years to find his part.

Default Hahaha!

You'd be surprised. I listed a part about 12 years ago in ebay, it didn't sell, I deleted the listing. About 6 months ago I got an email...
