Detailed Condition Breakdown ⚡ Electrical System (Defective Transformer):

The main unit powers on, but the illuminator bulb does not turn on. Disassembly and circuit testing confirmed 110V AC incoming power to the internal transformer, but 0V DC output to the lamp assembly. The internal transformer is non-functional and will require service.

🛠️ Recommended Restoration / Repair Paths:

• External Power Supply: Hook up an external variable benchtop/DC power supply directly to the bulb wiring.
• LED Conversion Kit: Ideal candidate for a modern aftermarket LED retrofit conversion kit for lower heat and longer bulb life.
• Component Repair: Replace or rewind the internal stock transformer.

⚙️ Mechanical & Cosmetic Condition:

• Mechanics: Unit has been torn down and cleaned. Stage/tray moves smoothly up/down and back/forth without binding. The nosepiece/turret rotates freely across all positions.
• Cosmetics: Clean condition with minor cosmetic scuffs and signs of normal laboratory environment use.
