I've been looking at building a set of Model 19 crossovers for my HeathKit AS 101's. It has a driver load very much like the Model 19. So far, pricing everything out the parts are coming to roughly 215.00 from Parts Express.
When I get some cash together I'll start a separate post with my parts list so that you folks can ok it. The inductors are where it gets confusing. I'm looking at Jantzen inductors, I think the 18 AWG ones will work but I'm unsure. Also there is no direct match for the 0.77mH inductor but they list a 0.75 mH inductor. I would think that it would be close enough.
