Hey all --
Working on bringing a Dasher D200 terminal back to life. There's a bridge
rectifier package that appears to have a short in it and I can't find any
info on it -- I suspect it may have a house part number. It's got a
Motorola logo on it, and is labeled "SDA314." In the schematic (
http://bitsavers.org/pdf/dg/terminals/014-000640_DASHER_D100_D200_Display_T…)
it's CR6.
This short causes the 5W resistors before the fuse to smoke and explode,
but the fuse is fine (thank goodness.) :).
Anyone have any ideas?
Thanks,
Josh

I would think, looking at the schematic that any 2A 600V bridge would do
in this position. If you wanted some error margin, the 4A 600V.
