I am attempting to repair an old Tektronix oscilloscope.
If anyone (in the US) is willing to donate a discarded/failed attenuator from a 2445 or 2465 or 2467 Tektronix please send me a PM.
It could be from the original or the "A" or "B" models.
[If you need CA3046, 2445/2465 A or B (only) type cooling fan, capacitors, TO-220 regulators or TO-92 transistors for your repair I have a few that could be traded in return.]
I could also trade a 2445 or 2465 type (hall effect sensor/SIEMENS) motor. It turns but squeaks which might be fixable with cleaning or lubricant? (No impeller or coupler.)
