Description

Manufacturer: Conoptics

Model: M25DS

Condition: Used. Comes in non-original packaging. This amplifier is in Fair cosmetic condition with minor scuffs/scratches from prior use (especially on top as shown in photo #5). It came from a system that had tape over some adjustments and a sign begging users to not adjust things ...and the knobs have been removed from the Bias adjustments.
The photos show the exact item(s) the buyer will receive.

Notes: This was removed from a decommissioned system. We verified it powers on, the power light and fan both work, and the DC Bias meter goes to approximately 400V both directions for both supplies. No other testing was done.

Please NOTE: This unit is marked for use with 230V AC, but we found it gave the full 400-ish volts with 120V input power; we are not sure if it may be limited in some other way with the lower main voltage.
No manuals, cords/cables, or additional items are included if not listed or shown.
