I'm looking for a reasonably priced Standard Module for the 577 Curve Tracer either in working or non-working condition. Please PM me if you have one for sale.
More 577 CT than 177 fixt. so rare.
Go to groups.io/Tekscopes and Tekscopes2 for Tektronix aficionados.
Also Vintage Tektronix Museum and Sphere Research in Canada.
Last resort, ebay and ham fleas ARRL.

I have a spare 177 fixture
was never tested so I would have to dig out my 576 hopefully after 20 years storage it works
Contact me if interested
