My implementation of the Inverse RIAA Network (IRN) for testing phono preamplifiers, based on the Andrew Russell article (November 2016, http://hifisonix.com/wordpress/wp-content/uploads/2016/12/Accurate-Inverse-RIAA.pdf). For MM and MC preamps. Surface mount resistors and capacitors (<=0.5% R, 1%C) for better than 0.025% accurate performance. Requires a signal generator with output impedance of 50 ohms or less for testing.
$30 includes shipping to CUS only.
11/16/2020 Unit is SOLD
PCB's are still available
For those who want to practice/improve surface mount parts soldering skills, I have (8) pcb’s available. Thirty eight 0805 part size resistors and capacitors are required. It’s not too difficult to do.
$5/board shipped to CUS only
PM if interested. Thanks.
