Tektronix 453 Bulb Replacement
« on: November 11, 2018, 06:23:35 am »
I have an old Tektronix 453 that works great except for one thing, B568 has a broken lead that prevents me from using the single sweep mode. I don't really want to chase NOS components but if anyone has any ideas on how to replace specifically B568 it would be very much appreciated.

Why does it have to be NOS?

The parts list says it's just a A1D neon bulb, available at DigiKey

Oh, thanks! Never thought to check to see if they actually still made those.
