Frequently Asked Questions

How do you handle heat from power amplifier stages?

Options include integrated heatsink fins, perforated ventilation panels for convection cooling, and provisions for attached heatsinks or fans — matched to your amplifier class and power rating.

Can you machine my front panel layout?

Yes. Send your drawing (STEP / DWG / PDF) with knob, display and connector positions. Panels are CNC-machined to ±0.1 mm with optional brushed finish and silk-screen marking.

What is the MOQ for custom amplifier chassis?

Sample orders start from 1 piece and production orders from 50 pieces, so you can validate sound, fit and finish before volume production.
