I have two 576 Curve Tracers. One has everything working perfectly and the
other has readout problems in the Beta display. I have two BAD and one good
155-0004-01 ICs. I know the problem is this part in the defective readout
board because swapping in the U976 part from the good board makes this
board work. The problem follows either of my defective U976 (155-0004-01)
parts. For what it's worth, the two bad 155-0004-01 parts fail
differently.? Still looking for a good replacement 155-0004-01 part.
Thanks,? Tom Bowers

Hi, I'm a new member of this group. My name is Tom Bowers. I have been a

Tektronix fan since the

late 1960s. I own an assortment of instruments and run an electronics

engineering and fabrication

shop from my home. I am looking for a readout decoder for a 576 Curve

Tracer, part number 155-0004-

01. I see a post from about a year ago, but can't figure out how to get

in touch with the person

mentioned (Steve Clark). If someone can provide contact info, or knows

of a source for this part, I

would appreciate the help.? ? Thanks,? ? Tom

Welcome to the group! Is that device missing entirely, or is the one in
your 576 dead?
