Very NICE reply, thank you !!!
Cinch makes a complete line of high quality solderable terminal strips, with many useful combinations available, at reasonable costs. They get my vote, I love 'em. Available at Mouser, Digikey, Newark, etc etc, reasonable also !!
Pictured above are a couple of C-56U / C-54U Cinches.
Between this post and my previous one, I just bought 18 film caps for $18.00 shipped, HIGHEST quality vintage ( decades old , not metalized ) caps, 0.0064 at 1,200 VDC at 2% tolerance. Bet it EATs a botique audio cap of today for $50.00 or less, .....for a dollar !!!

Terminals like the ones in the pic. These are for the final build.
My Goal is to use NO extra wire if possible, just use the component leads in a nice point to point layout. My Altec Model 14'a had the resistors directly soldered to the Lpads I will like to do this also. I still have some Vampire CCC solid core wire for these connections if I need to add any wire.
I also need to make a nice enclosure for my final build of the Z19.
Thanks
Certain crossover runs need to use wire.The single resistor leads are thin and rob dynamics.
I often use TWO resistors of double the desired value, well matched, in parallel, just to get extra dynamics, and a quieter background, a good tip !!!
On your CDE cap bundles, make them like spokes in a wheel when looking sideways, end-on at the group, equal wire lead lengths, bodies NOT touching, and a single termination point to attach appropriate wire and / or parts to.
Russian polystyrenes, K73-16 as I recall, would be a excellent superbly cost effective main crossover caps, in lieu of the CDEs. I just bought 50 pieces of 3.9 and 3.3 uF, 160 VDC, for $32 delivered. Polystyrene comes right after teflon as far as being way good - as a dielectric material
On a sensitive two-way high-efficiency speaker system, ( like yours, or my VOTT A7-800s ), we need to use DOUBLED-UP 12 AWG to each woofer terminal, from the crossover.
Also, for UTMOST quality, doubled-up silver wire, Kimber Kable AGSS, etc., from the crossover to the high frequency driver, with precise EQUAL lengths to avoid wire-ghosting !! I had drummerwill in Saint Louis wire-convert his GPA 604 MLTLS, early in 2015, and he positively LOVES the result with all of his DHT SET amps !!
Another great optimization is to use multiples and / or divisors of Bob Fulton's favorite audio length, 57 1/8th inches. Forty years later, some Japanese audiophiles in 2015 have "discovered" that three Fulton multiples, 14 feet, sounds "great" for a speaker lead length. Ha !! Only they are off about a 1/4 of a foot !!! Bob KNEW, discovered in the 1970s what was optimum.
Intelligent, conservative use of Cinch terminal strips rings my bell. Glad you ordered some Cougar.
