This is what my mic goes with. It is a 20 channel 2/3 octave analyzer with 60db range and 24DB slope per octave. Ch are from 24Hz to 16KHz all analogue. Added in a fast, med, and slow decay sw. Also bar or dot mode, and finally the source is from back RAC's or front mic input. Can stair at it for hours. I bought the cabinets from a local supplier. They come blank with handles,4x sides, top, bottom, feet, and all the hardware to put together all for $25 Can. (front panel is 3" x 12"). Think i have ten in total in my stereo system. I used 3/4" x 1/2" alu. bar stock to make equipment rails for rack mounting each unit. Here is some snips of the analyzer.

One big problem i see facing our community is "panel lettering". Used to buy the font, size, and color I wanted on a big sheet and dry transfer but those days are gone. Computers making our lives easier Grrrrrr

Beautiful! Love it! :D

Almost no one knows how to do perf board complexity like that anymore with the one-click-PCB-services available now.

Brings back memories of my youth and Forrest M. Mims III books littering my dad's workbench :wizard:

There is lot in the term P2P but more when one considers P 2 Cf 2 P is actually P 2 S 2 Cf 2 S 2 P With the odd exception being some of the machine made and inserted parts on plate threw hole boards. Hello DoDo bird soon.
Tightly wrapping one component's wire around another s or a pin, then, applying solder just seems to make sense for making the strongest , most reliable, (if done properly "no cold joints"), lowest resistance path, least suitable to induction of so many kinds connection between parts. With the wire-wrap boards, it is always easy to have what is needed to whip up a board (if needed) without all the chemicals etc, especially when it is a one of. We all find what works for us. I still have bags of donuts and various widths of lines and IC's for 6,8,14,16.18,20 etc also 2X sizes. !970's left overs.
Concidering our, make it, send it, pay for it, and get it on my IPhone world it has become,,,,,,,,,I would like to bring in a PCB // donut filled transparency just to see the look on their faces when i slide it out of the envelop. I'll have 2 please!
