My 19 build begins in earnest - H811b arrives....

Most Model 19 owners here on this forum prefer the original Model 19 crossover design over the Z-19. I know there are some people who like the Z-19 on other forums (and maybe some here), but I think the most important thing you need to keep in mind is that the guy who designed the Z-19 (Zilch) ended up using his Z-19 crossovers with non-Altec h.f. drivers because he himself couldn't get the Z-19 crossover to sound "right" with Altec h.f. drivers. This is documented in Zilch's own posts regarding the Z-19 crossovers. So, by Zilch's own example (and his posts regarding this crossover), the Z-19 is not ideally suited for use with Altec h.f. drivers. Keep in mind the original Model 19 crossover has high frequency EQ/compensation built in that makes it sound great with the 416/802-8g (or 416/902-8a) combination/specifically designed for this combination of ALTEC drivers. There are schematics on this forum to build the original Model 19 crossovers -- if you are building crossovers I'd suggest building ones that are intended for Altec drivers (and also happen to be recommended by people who actually own Model 19's!). GPA also sells Model 19 crossovers that are true to the original design AFAIK. If you're paying for shipping for drivers from GPA, they could put a pair of crossovers in the box and it would barely change the weight of the box/may not change the shipping price for your GPA driver order which means essentially free shipping for the crossovers with the purchase of GPA drivers/shipping. Of course building your own Model 19 crossovers from the original design/schematic is an option too.

Thanks for this. I take all of your points - and apologise if my original response seemed like a brush-off. Your words carry much weight, as does the collective experience of A19 owners.

It would certainly be simpler to get the GPA-recreated xo's. I guess with that taken care of I would only really have the cabinetry and horn building to take care of.

More to be said but busy working on copy router..

gdmoore28, I have started a thread, look for "Proposed Parts List for Model 19 Crossover". I'm also looking for input on that from the more technically astute members as I have some questions in that post as well.
I think the parts I have picked out are as good or better than the parts used on the stock crossovers that Altec built over 30 years ago. You can upgrade caps, inductors, probably find other things to push the cost of these crossovers well past the $1000.00 mark. The parts I picked out will keep it in the 215.00 range. Possible upgrades in the inductors, maybe, but even that wouldn't cost but an additional $50.00.
I think that it was a good idea to start a thread about building the Model 19 crossovers as I haven't come across anything that covers it well. Seems to be a popular crossover that does a lot very well.

Watching your Model 19 thread, Bill. Looking forward to it.
