i know i can get replacement chassis for nanao ms8,ms9 and sanwa pm1745 from pentranic.
i will have the yoke readings on a u5000 by this wednesday and by my reckoning its gonna be very close to those two yoke readings as its a switchable 15/25.
this could be an interesting thread as the failure rate on a lot of these type monitors is becoming higher due to age and there are an awful lot out there still,i have 16 ms9,4 u5000 and 4 pm1745
