Problem Agitation – What Keeps Your Audio Projects Stalled?
- High purchase price: Imported transformers often carry a 30‑40% premium.
- Inconsistent quality: Voltage drift and excess EMI cause audible distortion.
- Long lead times: 8‑12 weeks from overseas factories delays production schedules.
- Limited customization: Standard parts rarely match your exact power‑rating or footprint.
- Regulatory hurdles: Lack of CE, FCC, or RoHS certificates complicates compliance.
Result: Project overruns, customer complaints, and lost market share.
