schadow switch mounting information

In the 70’s and into the 90’s WBS used a Schadow switch in almost every product they built. Different buttons required different offsets so “GOLDEN RULES” of design were made up so each engineer was on the same page. I found two of those pages the other day and was fascinated. These drawings are both done by hand and are admirable.

Going to re-manufacture some WBS daughter boards

As a part of my school program, I’ve decided to take a shot at re-designing 2 WBS components.

First the 4-110 mic pre-amp for the M460 – M461. In the 90s WBS redesigned the card using 5534 but I’m looking at something even more modern.

Second the 109 cards. While at Revolution Recording, Joe D redesigned his version of the 109 card and it was a HUGE improvement. He described it as “taking the cheese cloth off the audio” and he was right.

The idea is to have a plug and play module available for users with a few new features not incorporated in past designs.

Once they’re done I hope to have them for sale on www.AudioAholics.com
