[Elecraft] xv-144 TX alignment question please.

Hi all,
      Wondering if someone can give me some advise please,

I'm driving my xv-144 with a TS850 which according to the ts850 manual has an output of 0-10dbm so i have chosen the input jumper settings within the xv-144 of 250mW as the lower setting is 1mW and i don't want to over drive the txvr.

 I've managed to position the tx coils as per the manual but have stripped the alignment tool and have been taking to it(the tool) with a knife to try adjust the slugs with little luck on obtaining a grip on the slugs.

 What i'd like to ask about is the voltage measured at TP5 and how critical is it that the final voltage measured is under 10v as per the manual.To achieve the 8-10w drive from the xv-144 that i require for my amp i'm measuring just over 13v at TP5 while adjusting the input attenuator R22.

Wondering if this is ok (?) or if i should persevere with peaking the tx coils (?) 

I'm concerned that if i adjust the jumper setting to 1mW positions that 0-10dbm will be over driving the xv-144.

Any advice more than welcome and appreciated.
Kind regards
Paul
