Yeah .2v which is in spec now
Have fixed the loose CRT and var knobs now as well. Reassembly in progress.
Robert deserves the jammy git award for that 8640B
And my eternal envy -- for I desire a 8640B. Or any boat anchor RF gen. When I've got that, all i need is a SA. Or so I think.
Meanwhile, neither the repair queue nor the project stack are shrinking, but it is funnier to put them off and dream of gear...
Did a somewhat deep dive (deep since it did require me swimming in pretty uncharted waters of knowledge) into a 3-phase motor yesterday, for my neighbour. He's had it rewound by a winding shop but it does not work. We tried to find out if the winding shop had put it together correctly or not.
At any rate, it was moot, because something he's done to it -- perhaps as a consequence of faulty rewinding, perhaps not, it is thoroughly roasted. Again. We first tried to make sense of it by measuring ohms, but that did not help. Then I tried inductance (DE-5000
). Made more sense, but not enough. Finally, cracked it open, just to reveal a blackened winding.
