Hi group,

I bought a Tektronix 576 curve tracer a few years ago in the US and it was
damaged during shipment to Europe. The CRT got a hit and was shattered to
pieces.
Which CRT is a suitable electrical - and if possible mechanical-
replacement if I ignore that the original CRT has 10 vertical divisions?

Someone told me, a CRT out of a 5103 scope would be a good fit. What do you
think?

Best regards

Jan

?I was e-mailed the winding data of the HV transformer some years ago by a forum member since the 576 in my posession also had the leaky transformer. The winding data can be found in the manuals section of KO4BB. Look inte "Root" folder of TEK. A friend of mine printed a new plastic bobbin. I successfully separated the two ferrit core parts by heating the transformer in a small oven until the parts could be manually separated without using force. Then, using the winding data, reproduced the transformer, using a home built winding fixture (and patience since the secondary winding is some 1000 turns 0.1mm dia copper.) It is important to wind the HV portion using HV insulation between the layers and also by always starting a new layer from the same side as the previous layer in order to avoid internal flash-over.

Another problem was the LV power supply section. Aging carbon type resistors way out of tolerance and also leaky electrolythic capacitors is a problem with older equipment.

Jan, I also still have the tubes and they both still work they are just
VERY
high hour let me know if you are interested. One is extremely dim the other
is dim but readable and double peaking using a 3d printed viewer it might
be
usable. Not idea but It might get the instrument off the ground.

That's the 577 that shares the crt with the 5000 series. With the 576 you
have to find one. Nobody's come up with an LCD replacement (yet) but I
would expect to see something eventually.
