Z19 crossover vs. GPA off the shelf

Here is a thread on them: Z19 Crossover
I have no experience with the GPA crossover, but I felt that Z19 was an upgrade over the stock network in the model 19.
I want to say that I spent about $200 with the parts I used?
With that said, you could probably get away with $150 or the sky's the limit if you want to go with boutique parts.
If you are comfortable with a little solder, I'd suggest building one. I like to tinker and so being able to choose each specific component to me is a big selling point versus an "off the shelf" network.

Here is an image of the schematic:
and here is a layout one fella put together (not me). Sorry about the photobucket garbage. Couldn't find a version that didn't have it.

My avatar is a pic of my build of a stock Model 19 build. I read all I could about the Z19 build and I saw where several folks went back to the stock design after building it. To me that was very telling.
I compared the schematics of both designs at the time and and there was just a few minor differences, almost the same design.
Here is the post on AK about mine.

My Altec Model 19 crossover build
Just finished the first one, the second is almost finished. I built the base from 1/8 thick fiberglass that is used in industrial electrical panels, purchased from McMaster Carr. Actually, all the terminals and hardware was purchased there also. I really like turret board construction, this is...

Marantzfan left the original crossovers in these 19's he restored so maybe I will recap them one day just so I can compare. Actually the guy I got them from took them out and a couple days later the estate sales manager called me because he had found them and the original woofers.
I will probably just go with the stock design from GPA. The reason I asked was because I had been down a similar path before with some bozaks and the Tobin mod to the crossovers. I liked the change initially but after awhile realized that I preferred the original better overall. thanks everyone
Sometimes you gotta stop and think about modifications to the design of crossovers. Although it may be 40 years ago, they did have the same components we use today and if they took the time to test and listen to what they were putting together, their ears were as good as ours. No, they didn't have the computer testing capabilities we do today, but maybe their ears were better trained. Especially on the top end stuff. Replacing those old caps etc with what should be considered better versions to day are most often the biggest improvement one can make.
The good thing is this little culture of ours here will find the ones that weren't designed as well as they could have been.
