2 Paramount Voltages Problem

[AudioDave]

Doing the voltage check on my first completed 300B Paramount and have 2 voltages that are not right.  Terminal strip #10 reads 0 VDC and should be 233 VDC.  Terminal strip #13 reads 0 VDC and should read 94 VDC.  All other voltages are perfect.  All solder connections look good visually.  Any suggestions?
Thanks!

I forgot to add that terminal strip #11 is also a tad bit high and reads 229 VDC and should be 164 VDC.    I forgot to mention that these readings are with the Soft Start board installed.
Thanks for any help you can provide

In doing further research on this forum I found a couple posts by folks with the same question I had about terminals 10, 13, and 11 and it sounds like I am good with my voltage readings.  Does anyone have the most current listing of voltages that I can check against just to make sure I won't damage anything?  The list I am using from my soft start manual apparently is not correct!
Thanks!

It looks like the soft start manual has some errors. 

T10 should be 0V.
T9 will be whatever OB is, and is adjustable with the trim pot.

If you believe there is an error, you can post the IA, OA, IB, OB, KregA, and KregB voltages here and we can assist you.  Beyond that, the terminal strip voltages are a small sampling of these voltages.

Thanks Paul,  yes T9 reads 175 VDC the same as OB.  The only voltage that is questionable is T11 which reads 230 VDC and my soft start manual shows 164 VDC.
Can you provide me the recommended voltages for IA, OA, IB, OB, KregA, and KregB?
I really appreciate your help!

It seems that we need to revise the manual a bit.  There will be little to no current flowing through those Zeners once the amp is running and warmed up.  If you have 300V at OA/IB/+regB, then the voltage at terminal 11 is unimportant.  (In the Kaiju, we do not have voltage measurements on these terminals for this very reason)

Thanks Paul !!
