Thanks for the responses. The rectifier I bought was a NTE53004 which
looks like it will handle 1000v and 10A, but what threw me was the
different form (this one has a hole in the middle) I will look on the
board to see if I can figure stuff out as to the orientation. Thanks
again

Hi Alan,
As Jim indicated, these things aren't critical as long as they can
handle the volts and amps of the application and are over-rated
sufficiently to handle the sub-standard heatsinking.
Re orientation, they are usually marked with '+' and '-' on the DC
terminals with the AC ones being marked either AC or '~'. The two AC
terminals are interchangeable. Often the '+' terminal will have a
chamfered corner, dot or some other marking to reduce assembly
errors. The PCB overlay usually (always, if I designed it) has
similar markings as well.

You need something that will handle at LEAST 8 amps (so it'll run
cool) and
at least 600 volts.
The OEM's are marked as 1000 volts 10 amps - 8amps at 1000 will do
as will
10 at 800 .... GIve me a yell if you have trouble finding one. IF
you'll
send me a the board number, I'll tell you what the original was.

Subject: [7x12minilathe] Mini-lathe controller rectifier question
I have a Homier Mini-lathe with a shorted bridged rectifier. I
removed the rectifier to see if I could buy another and have lost
the
darn thing. Does anyone know the part number? I had a rectifier
on
order but when it came it, it did not look like the old one. Also,
the rectifier is in the lower left of the circuit board when
looking
at that side, which way was the flat on the rectifier? I seem to
remember it was up and to the left. Any help would be appreciated.
Thanks
Alan
