Hello,
Thanks, I agree that the capacitance is not correct. They are notes from previous owner. Perhaps measured with wrong gear.
What remains is the mystery..
Last example: CA4 4.5 600 76-19
Resistance:
1-2 1,2683 Kohm
4-3 1,2682 Kohm
1-3 159,01 Ohm
2-4 157.27 Ohm
Voltage drop in DIODE mode in any direction
1-2 1,136V
4-3 1,137v
1-3 0,203V
2-4 0,201V
I put 6v ac @50hz on pin 1-2 and get 1,5dc on 4-3
