   The permanent case from China arrived.    Sixteen holes were drilled, eight on the front and  back sides. Four for each cabinet, two for the woofer and two for the horn.    The images show front, back, and diagonal side views.    The disk drive storage units are shown in one photo. I have one four terabyte  drive and two one terabyte drives for a total of six terabytes storage.    The four terabyte drive is the general collection. A one terabyte drive is reserved for my blu-ray collection and another for UHD 4K videos.

What are shown below are original, ideal, and real schematic representations of the crossovers and SPICE analysis results. Diagrams follow these. They are, in order of presentation, real, ideal, and unmodified original. In these diagram, the layout is correct but the values are not. The Valencias in my possesion have a single 24uF capacitor instead of 11uF and 10uF in prallel, which equals 21uF. The inductors are 1.5mH instead of 1.75mH. The 8uF capacitor in the horn circuit is correct. The network provides 0db-20db adjustment range and a 12db roll-off. These, after my modification, became second order Linkwitz-Riley hi-pass/lo-pass filters.

Included here are photos of the networks in the temporary case made from a plastic kitchen utility food container: The two large red capacitors sit atop the original black capacitors and are connected in parallel. A view of the connection to the receiver inputs: A better view of the crossover case output side to the receiver: This is what the networks look like inside the case. The circular metal shapes are the resistor L-pads. They were removed from the circuit to make two independent filters, one hi-pass for the horns, one low-pass for the woofers.

   The crossover is complete and in use. The difference is noticeable. The networks, four filters-two hi-pass and two low-pass, are in a plastic container intended for kitchen use. A permanent case I ordered from China will not arrive until late September or early October.    The phono RIAA equalization preamp is assembled. The pcb did not fit the case but I clipped the corners off and can get the card into the case.    An external power supply is needed to run the preamp. I'm drawing up a parts list. The maker of the preamp pcb included a mini power supply pcb for use with the preamp. I'll be using that circuit to power the preamp. I'll need another case for the power supply. This time, I'll order larger than I need. The specifications for the cases I'm ordering do not include interior dimensions. Photos to follow.
