For Sale: Vintage tech looks to be complete and in good shape but untested. This is a heavy piece.
Info from https://tubesound.com/leeds-northrup-bridge/ :
The craftsmanship and build quality of this device is truly remarkable. I cannot fathom how much money it would cost to build this same device today using identical components. The unit consists of a large magnet, floating mirror, bulb, magnifier, panel scale, brass and silver switches with no measurable resistance, and a large number of precision resistors that were hand-wound and perfectly balanced using the finest balance bridge equipment available at that time. Truly the highest laboratory-grade accuracy that was possible — BEST of best. Resistance accuracy should approach 0.1%. For this reason, the unit makes a fabulous (true) precision resistance box for checking calibration. This gives it a modern “use” instead of sitting on a shelf as a discussion piece.
