Re: Residential Lighting with LEDs: Retrofitting the Pink Ranch
Digging around on an old thread.... My back porch light fixture is designed for an Olde School A-19/A-60 bulb (as I recall the numbering) with an Edison base. The typical 60W or 100W incandescent. Down to one spare incandescent bulb, so I am looking for a LED brand/model designed to work in +100F do...

Nichicon "Audio" Electrolytic Caps
I typically choose Nichicon (and also Panasonic) caps for new builds as well as repairs. Each brand has a huge number of variations that are difficult to select. I typically look for 105c and long life, but there are a ton of other variants. I stumbled across this at Mouser: https://www.mouser.com/n...

MEP-250 Bridged-T equalizer
The recent thread regarding "negative impedance converter" interestingly wandered into a subject I've been pondering recently, namely the ITI/Sontec/and perhaps current Massenburg EQ designs. Many years ago when I was a very young studio recordist, I recall being blown away by the original...

Re: A Modern Loftech TS-1 Audio Test Set
Hiya John. Part of my biz these days is finding/restoring analog recording desks. When "flying" through a few dozen channels is my Olde Method using a square wave to quickly test the EQ circuits on each strip. Go/No Go as it is.... Sidebar....more often than not: 1. Ancient electrolytic co...

Re: "fingers" on edge connectors
I regularly encounter edge connectors on the older desks that I service/restore. SSL, MCI, Trident, and API just to name a few. I would NOT use that style connector on a new design except for the fact that the 15 pin format is standard for the highly popular 500-series "lunchbox" gizmos......

The standard connector for 500 series modules and the "lunchboxes" is that infernal edge connector which API began using decades ago.

Neumann SE66
Keep in mind that the pic I linked was the original setup in Calif. Ed "broke down" the pair of linked lathes into one single lathe. So, lots of spare parts here! <g>
