Sanyo 20EZ B+ pot identify

[cornishHen]

I've been trying to figure out a video problem with a dk (2 board) boardset and a Sanyo 20 EZ.  I decided to cover my bases in troubleshooting the problem today and checked the B+ voltage on the Sanyo.   I found it was running on average at 91V...well below the desired 108V.  I tried to adjust the B+ pot and it seems the pot is toast.  It spins and has a small piece of metal bent/broken. 

Can anyone help me identify the B+ pot/suitable replacement?  Also, the R-Drive pot is partially broken but appears to adjust the red intensity fine.  From what i'm seeing that pot is VR254 8ohm-200ohm?  I found Bob Roberts has a nice selection of pots at:
 http://arcadecontrols.com/BBBB/pots.html.

Thanks for any help!

VR254 - 200 Ohm   (R-Drive)
VR601 - 5k Ohm     (B+)

Decent Schematic:

There's a few more on ArcArc if you need those as well. Some slightly older versions, etc.
