Recreating An Old DIY Leslie Crossover

I have a unique Leslie speaker setup that is a modified Leslie 925 from the 70s, but only the top horn section for use in a guitar rig. I'd like to copy this crossover that was used in the original that I am copying, looks like 3 components wired in a series>parallel setup but I'm having trouble sourcing them for mine.

They look to be:
1. T.I. 36uf 100v NP K 85C
2. Sprague Atom TVAN ? 10uf (100v?) NP 85C
3. NTE 28W 8.2ohm

Are there modern and new equivalents of these components that I could use for my build? I've come across a few vintage JBL crossover units that look to have some of the same components, but not all, but not sure if it's even worth it to scavenge old parts if newer stuff with the same specs are available.

Thanks for any help!

Here are pics from the original that I am trying to replicate

Looks like the 36 and 10 are in parallel, so that makes a 46 uf cap. 47uf is a common value and well within tolerance.

NP means non polarized, and its an electrolytic cap. A 47uf 100v NP should be available at any of the usual parts vendors.

The resistor is a wirewound type. 8 or 8.2 ohm should be available in 25w or higher at the same places.
