: : : : I need a service manual for a Motorola R2001-A
: : : : service Monitor. Especially need schematic for
: : : : power supply section, since I know there is a problem
: : : : there!
: : : : Location: Colorado USA Fax: 914-831-1872
: : : : email: mohaase@nilenet.com
: : : Do you still need this manual ?? I have it I can copy power supply pages for you.
: : : What is wrong with unit? Don
: : Yep, I still need it.
: : The processor board has about 2 volts or less powering the logic. Scope tube filament glows
: : and there is a large round dot on face of tube when powered up. There is a 2-3 watt ww 1 ohm
: : resistor in the power supply that got hot enough to melt the solder on the leads.
: : Thats what I know so far. I took the power supply electronics chassis out and inspected it,
: : but did not take the power transformer out to try to run the supply on the bench. That will
: : probably be the next step. If I knew the power supply output voltages, I might try to kludge
: : up some external power supplys to check out the rest of the unit.

: This power supply that you are talking about is it in a mateal cage with a lot of screws
: .Located inside in the rear middle of the unit?? Send me a part number.. Don.
Yes, thats the one. *LOTS* of screws. Ill see what I can find, but it will probably
take me a few days to get it out amd look at it again.
