Heresy 1 crossover schematic

I see that the schematic has John Albright's mod. My Heresys are old and since I am rebuilding my x-overs in other speaker, now would be a good time to do the Heresys.

What are the specs for the inductors? (wire guage)?

Is a Litz type wire better to use than solid core for this application (AL only uses Lits on the HF drivers)?

Do inductors even wear out (should I just replace the caps)?

The ALK's are just too expensive to do 4 for surround speakers for HT (using a Denon SS Receiver). Does anyone have a good design that is cheaper? I was thinking about just replaceing the caps with Solens and replacing the transformer and inductor if needed.

Thanks,

Chris

I have two sets for HT surrounds. When I first bought them, I waqs really surpised that "for some unknown reason" the older ratty pair sounded way better that the newer ones. The parts should explain why:

Older version:

K77 Tweeter

K55v Mid

K22 Woofer

Thpe E Crossover

Newer Version:

K77 Tweeter (Plastic)

K53 Mid (Plastic)

K22 Woofer (uh, not plastic!!)

Type E-2 Crossover)

By the way, I realize that it is because the Heresys are sealed, but the crossovers look new in all four.

Like I said above, I am lookinmg for an inexpensive rebuild (if necessary) for Home Theater surround duty using a Denon 5800 receiver.

Thanks,

Chris

Thought that I would bump this one up top to try to get an answer.
