Hello again,
It's been a while since I wrote and had to say goodbye to my 465 oscilloscope, but I managed to find another one and luckily without any issues.
The serial number is 109003, which is I understood one of the latest. (Not sure though)
Anyway, I did a check on the power supply voltages and the big capacitor's ripples between the plus and minus on the Elco itself:
C1512 (550uF) 79V and 300mV ripple,
C1513 (1200uF) 74V and 1V ripple,
C1542 (5500uF) 23V and 1.5V ripple,
C1552 (50009uF) .2V and 700mV ripple,
C1562 (3000uF) 12V and 1V ripple.
Any idea if this is acceptable ?
It might be wise to replace them in the future, but for now I just leave it as it is and use the oscilloscope it was made for.
Thanks again and have a lovely evening,
Wilfred
