Here is what I would do:(1) Crossover wiring is inadequate, Double UP all wiring with EXACTLY equal lengths of wire. I am talking about the 5 Red and 2 Green you show. Two EQUALLY long electron paths are better than one. UN-EQUAL lengths will "ghost" and be a degrade.
(2) Film capacitors, for best sonics, should not (a) touch each other or (b) other parts like inductors, or (c) the chassis if its a metallic chassis.
See my photo, above, of one no-touch solution.
(3) Wiring from the crossover to the woofer should be paralleled EQUAL length heavy wire, two conductors for the woofer positive, two conductors for the woofer negative.
I often use doubled-up Fulton Brown speaker wire ( about 10 AWG, each run, or 7 AWG equivalent ) or doubled up 12 AWG Mil Spec copper-silver wire ( 9 AWG equivalent ) from crossover to woofer terminals. Huge difference with SET amplification.
(4) I would think every film cap bank in there needs to be bypassed with somewhere between 2.2 to 10 nF of a HIGH quality film cap, as a minimum effort. Do that, only AFTER you ascertain correct operation, and the main caps break in.
Its going to BLOW your mind when you discover such a small value bypass film cap on the tweeter, will audibly improve the low end !! Ha, that will be cool for you to hear and discover.
Have fun.
