Estimated Market Value
Based on the photos and visible specifications:
- Untested: $80–150
- Tested and fully functional: $175–300
- Professionally serviced/calibrated: $300–450
If you can demonstrate that the output varies smoothly from 0–140 VAC under load, the value is typically much higher than an untested unit.
