One Door Deeper: The Bench Pass

The public case file tells the story. A Bench Pass shows you what happened on the bench.

This paid educational subscription opens selected Riddim bench records: inspection photographs, voltage charts, scope captures, failure analysis, component decisions, circuit changes, and measured results. New records are added as worthy projects find their way through the shop.

Bench Pass is built for technicians, builders, and serious students who want to understand the reasoning behind the work…not just see the finished amplifier. Customer information is removed, and certain proprietary details may remain behind the curtain.

Access begins with a short application. Tell me what you work on, what you already know, and what you came here hoping to learn. If it’s a fit, you’ll receive the available subscription options and your way into the archive.

Bench Pass provides educational documentation, not live repair support. Tube equipment can retain lethal voltages even when unplugged.
