Ibanez AD202 Multi Mode Analog Delay - BBD Rack, Serviced & Calibrated, 230V EU

Ibanez AD202 Multi Mode Analog Delay. 2U 19" rack unit, made in Japan, early 1980s. Serial 303510.

A genuine bucket-brigade analog delay — no digital circuitry anywhere. Three cascaded BBDs (2x MN3005, 1x MN3007), giving 60–400 ms of delay time in delay mode (factory spec).

FIVE MODES

Delay · Doubling · Flanger · Stereo Chorus · Normal (bypass)

IMPORTANT — VOLTAGE

This is the European factory version: AC 220–240 V, 50 Hz. It will NOT run on 120 V without a step-up transformer. Please make sure this suits your setup before buying.

CONDITION — ELECTRONICS

Fully working. All five modes tested and correct. All I/O verified: CH1, CH2, Effect Out, Dry Only Out, Footswitch. No scratchy pots, mode selector switches cleanly, all knobs present and turning smoothly.

WORK CARRIED OUT

Disclosed in full rather than hidden:

- Clock trimmer VR114 (delay mode) was dead. A previous owner had simply bridged it with a screw. Replaced with a new 10k trimmer.

- IC112 (4049 hex inverter, switching logic) replaced.

- Recalibrated strictly to the factory service manual: VR114 set to 11.75 kHz at test point CP4, delay mode, Delay Time fully CW and Width fully CCW. Factory spec is 11.5–12 kHz. Width sweep cross-check also within spec.

- Factory BBD bias and output balance trimmers deliberately left untouched.

Service manual and schematic (PDF) included with the sale.

CONDITION — COSMETIC

Honest player-grade patina, please see photos. The front panel has several paint chips, the largest around 8 mm across, where surface rust had formed. Rust has been removed mechanically. Deliberately NOT repainted — matching colour and sheen on a 40-year-old panel is not realistic, and a visible touch-up reads worse than the original wear. The next owner can decide differently. The top cover shows scratches and a small dark mark (see photos). All front panel legending is complete and undamaged.

INCLUDED
