It might help if I posted the values of the capacitors that were originally in the scope. I'll do this below in the quoted text.

‎Hi folks,

Here's my proposed parts order on Digi-Key, except that I haven't decided
between the first or second set of tantalums. The caps below those are to
replace the large C1412, 14, 42, 52, 62, and 72 capacitors. I tried to go up
a bit on the rating of both the capacitance and the voltage, but was hampered
somewhat by a lack of choice when only purchasing one or two of each. I'd had
Nichicon recommended to me, so I stuck with them where I could. Apparently,
Nichicon sold their tantalum capacitor manufacturing to AVX. I don't know
about Kemet, but couldn't find Nichicon near those specs. Also, I haven't yet
received the circular PCB's, so I assumed from the photos of them that they
can accommodate a range of lead spacings. Just thought I'd run it by you all
before I place the order in case I'd be advised to change anything.
To replace the tantalum I broke (C1091), and the other one I removed (C1093). Originals were 2.2μF 20V.
