Yes I am going to have to make some new pathways - no doubt about it. All my PMs here on Hostboard have been deleted - I guess because my account was inactive.

I also searched my emails last night and found an order I placed with GPA for a the drivers for this build. I never received a reply to this email - I asked Bill for payment details and to hold the drivers for me until I could arrange suitable shipping to New Zealand. I can only suppose my email went to his junk box.

About this time I encountered the first of several seizures in fairly quick succession. They are a strange thing - like a reset button almost. When I come round from them it takes me a long time to work out who I am.. and lots of extraneous data seems to just fall by the wayside, along with stresses, cares and worries. So I end up feeling refreshed, but at a price. I've found recently that going back over my emails and messages can help fill in the blanks... but I hadn't thought if that last year. Anyhow.... onwards!

It will be 6 months or so before I have the funds again for the drivers.... (oops, I bought a Londinium espresso machine....). But I can work on horns and cabinets as of now.

Is there any danger of GPA disappearing between now and then?
Welcome back and I'm glad you're OK! I think it's a safe bet that GPA will still be around in 6 months. However, of course they won't be around forever so I bought a pair of spare GPA diaphragms a while back in case I ever need them or want to swap them out some day in the (hopefully) distant future. Personally, I would build your speakers using the original Model 19 crossover design and not the Z-19's. Zilch was an intelligent and knowledgeable guy, but he really was a JBL expert and only "dabbled" in Altecs. He ended up using his Z-19 crossovers with non-Altec h.f. drivers--he couldn't get them to sound right with Altec h.f. drivers so what does that tell you about using Z-19's with Altec h.f. drivers??? The original Model 19 crossover is a masterpiece in my opinion. I own two pair of Model 19's and love them even more now that I've recapped both pair of crossovers and did the crossover ground modification that has already been discussed in this forum several times. Best of luck with your project!
