Original reel motor wasn't running at a low voltage/current I like to see so I installed another one from a Kyocera. I also rebuilt the cam motor.. I typically check for less than 0.5V startup voltage and less than 10mA no load current from 0.5V to 6V, at 2V it should be somewhat difficult to stall it.
I have rebuilt 4 reel motors also successfully and 1 failure(immediately) so far..after more than a year of usage.
W&F is 0.04 to 0.06 Wrms. Pair matched all the Wiima caps.
Followed the detailed calibration process shown in the SM. I'm exhausted but the deck is done..
But what a beauty, nevertheless , I will stay away from the model. It sounds stunningly on all tape types.. other than the tape bump, I really can't tell the difference between source and the tape.. 
Is this the most computerized consumer Nak ? 1000ZXL is more of a pro unit.. I don't mind work hard for something like that...
