[Info-vax] rx2620 power supplies / VRM voltage low

[Carl Friedberg]

HP service is reasonably priced. I believe we pay under $1,000/year for
Next Business Day hardware support for an RX2600 (not 2620) on a 3-year
prepaid contract. There was about a $1,300 charge for return to maintenance
(no inspection). If you need a referral, as usual I recommend David Witt at
Flagstaff Technology (contact me off list)

I know that research institutions can be very cheap, and they have graduate
students as slave labor, but surely having an instrument on maintenance is
not an unreasonable expense for a lab?
