Hi Ozan
Intensity control works except in X-Y mode. In X-Y mode the spot remains displayed with the same intensity no mattter what is the intensity knob position.
Exercising the VERT MODE / HORIZ MODE switches doesn't improve X-Y mode intensity modification.
I set both Intensity & B Intensity knobs to 9 o'clock position.
At CR1561 anode, I get 1.12V
Output (p8) of U1560 is : 14.1V
Note that changing intensity knob position does not affect the voltage reading.
I also measured all the pins Voltage (all in V):
(1) .250 (9) 0
(2) 1.251 (10) 4.18
(3) GND (11) 15.02 - VCC
(4) .448 (12) 5.022
(5) 0 (13) 4.99 - VCC
(6) .832 (14) .097
(7) 1.055 (15) .905
(8) 14.11 (16) .246
