Balanced Attenuator PCB pattern (PDF download) [04105151]
PDF with the PCB design for the Balanced Input Attenuator for Audio Analysers and Scopes (double-sided).
Note that while this could be made by etching with careful alignment and then soldering wire through for each via and double-soldering components that make connections on both layers, it would be quite impractical. This pattern is mainly provided as a reference for the commercially-manufactured double-sided boards that we supply.

Balanced Input Attenuator front and rear panels [04105152/3]
Front and rear panels for the Balanced Input Attenuator for Audio Analysers and Scopes, coded 04105152 and 04105153 respectively.
Made from PCB material with a red solder mask and white silkscreen printing with all required holes routed out. These replace the front and rear panels of the case. Both sides are covered with a copper layer under the solder mask with an exposed area at the rear to make contact with the main body of the case, for electromagnetic shielding.
170 x 53.5mm each.
