Acoustic Zen Crescendo speaker crossover capacitors ... who makes them?

This link should take you to a slide show. The first pic and last are the original board with no upgrades.

There is also an additional board on the very bottom of the speaker that I have not touched as yet. It is for the bass drivers. Unfortunately it contains two 1000uf electrolytic caps! The two resistors on the bass board are sand cast and will be replaced with Mills MRA 12. As for those 1000 uf caps I will think on my plan of action. I cannot believe how many parts are in this crossover. This is not your simply first order type.

I believe it is a 3rd order Linkwitz/Riley design. 

This is the amp I am using to drive them right now. It started its life as a Cary Rocket 88r. I modified it to the hilt with....

- all high quality film caps in the power supply (Clarity TC, ASC, Obbligato)  and increased the capacitance. Needed to add a wooden expansion chassis to fit the film caps in the power supply. A double decker build. 
- Arizona capacitor blue cactus coupling caps
- Western electric NOS hook up wire
- Mills MRA resistors
- Moved the RCA jacks right next to the input tube and also made more direct connection in addition to shortening the signal path
- removed all electrolytics caps and replaced with Clarity and Theta caps.
- removed binding posts and use Teflon posts to "clamp" the output transformer leads directly to the nude speaker cable.
- direct soldered high quality power cord

There is more, but you get the idea....

Here are some pics.

Outstanding and can't wait to hear your report after 300+ hours; those caps should be at their best by then...

Wow that's some ambitious work Grannyring. I've recently been using clarity TC caps and have had very good results. Enjoy!
