Hey Folks!
First post and I'm just a tinkerer....
So I'm replacing the PS Caps on my Tek 475A....
I cannot find the same capacitance ratings for replacements.
I've read Ron Childress' Tek 465 PDF and it was VERY helpful but as a noob I question the selection of replacement capacitor ratings....
Part Purpose Original Replacement
C1512 +110 VDC Filter Cap 550 uFd, 100V 560 uFd, 160V
C1513 +55 VDC Filter Cap 1200 uFd, 100V 1200 uFd, 160V
C1542 +15 VDC Filter Cap 5500 uFd, 30V 5600 uFd, 35V
C1552 +5 VDC Filter Cap 5000 uFd, 25V 5600 uFd, 35V
C1562 -8 VDC Filter Cap 3000 uFd, 35V 5600 uFd, 35V
I don't question Ron of course...esp because his scope works now....But I just cant get around choosing a 5600uFd cap in place of a 3000uFd one (C1562)
I have more than these caps to replace and I really need to understand the logic behind it!!!!
