Hello Wiredbecker! I have a pair of V1.1 crossover PCB's purchased from Zilch in 2012. Could you please tell me if V1.1 is the latest version and, if so, could you please let me know how to get a copy of the instructions that came the the PCB's? Thank you!

Hello again Wiredbecker. Can you send an updated Parts Express BOM for the Econowave boards? I'd also like to know if there are any suggestions for a replacement for the L2 1.5mH iron inductor 0.126 dcr that will mount on the PCB? The part number I have for the original was 266-552 but no longer available from PE.

PE has a similar 257-652 but it is 0.24 dcr.

PE 257-652

Madisound a similar one with 0.146 dcr

Madisound SI1.5

Please let me know if there is a drop-in replacement for the 266-552 or if either of the above would work. Thank you!

Hi guys, (mods, please remove if not aligned with the rules here)
I built a pair of Advent Legacy Econowaves a few years ago...they sound great! I am retired now and downsizing my audio gear. I would put these things up for sale, but locally, nobody would know what they were value-wise. Plus I do not want to ship them due to weight, and shipper's negligence. I figure it would be better to part them out and offer up the parts here. Would anyone be interested in some or all of the parts? Zilch board, all PE parts as listed by wiredbecker above. Please PM me if interested and we can negotiate pricing. Thank you!
