Hey OP,
One thing to be aware of is that modern film caps have a lot lower ESR than they used to. With so many caps in parallel, it may be worthwhile to measure the ESR of the original assembly (I see 4 or more caps in parallel) and make sure you replace with equivalent ESR, or add R as needed.
You can use Dayton DATS or a jig for Room EQ Wizard to do this.
They used to believe that ESR was a big contributor to the sonic characteristic of capacitors, but that's been pretty much disproven. Whatever the reason it isn't there.
Best,
E
