Mint / Complete Unassembled DIY Kit

This kit is complete with all originally supplied parts and has never been assembled or used. Because it is an unassembled electronics kit, it has not been functionally tested as a completed 500-series module.

DESCRIPTION

Link Audio Design F22X 500-series dual resonant analog filter DIY kit, complete, unused, and never assembled.

The F22X is a flexible analog filter module intended for both corrective filtering and creative tone shaping. It provides independent high-pass and low-pass sections with steep 24 dB/octave slopes, variable resonance, and continuously variable dry/wet blend controls.

The high-pass section covers approximately 20 Hz to 500 Hz with a switchable fine range, while the low-pass section extends from approximately 2 kHz to 22 kHz with an extended lower range. Both sections provide variable resonance of up to +/-15 dB. The design also includes output level trim, relay bypass, a balanced THAT 1246 input stage, and THAT 1646 balanced output stage.

This listing is for the complete unassembled DIY kit, not a completed 500-series module. Assembly, voltage checks, calibration, and final testing will be required by the buyer.

Build documentation is available at linkaudiodesign.de website

The kit has never been assembled or put into service and has remained stored in its original Link Audio Design box. Please review the photographs carefully; they show the actual kit and components included in the sale.
