My Tektronix 4051 has been sitting on the shelf since the analog board blew several years ago. I think it is about time to get back to it and fix it. Back then the ceramic module with 8 laser trimmed resistors blew. For some unknown reason. Since then I built a replacement out of 40 pieces of precision 7.5 ohm resistors and also gotten a NOS original Tektronix module as well as a spare analog board (which has been sitting is the woods of Oregon for quite some time, though).
Now I have hooked up the PSU and the analog board on the bench with some wiring in between so that I can take measurements on it while it is running.
What would be great is to have dummy deflection coils consisting of resistors just to see if I can get it to operate properly. Unfortunately the 4051 itself is in storage quite far away so I cannot take any measurements on the coils myself.
Is there anyone that has their 4051 (or 4052 I guess) nearby and could measure the resistance of the deflection coils?
