[j-nsp] M20 power supplies and the different part numbers

[Nicolaj Kamensek]

Hi list,

I am currently looking for "good" m20 power supplies(AC) and want to 
make sure to buy the correct ones. So please just confirm or correct me:

740-001465 are the possibly "bad" ones(each revision?)
740-007311 is ok, no matter which revision

(Feel free to offer me those parts off-list)

Thanks in advance & best regards,
Nicolaj Kamensek
