FYI
Bryston changed their serial number layout when they moved their manufacturing facility to Dwight, Ontario.
Your 14-digit serial number contains the exact manufacturing date embedded directly within the middle digits. It breaks down into three distinct sections:
* **Digits 1–7 (Product Type):** Identifies the exact model/preamplifier type.
* **Digits 8–11 (Date Code):** The manufacturing date, formatted as **YYMM** (Year/Month).
* **Digits 12–14 (Production Sequence):** The unit's specific production number for that month.
---
### How to Decode Your Date
Look closely at the **8th, 9th, 10th, and 11th digits** of your serial number:
* **Digits 8 & 9** represent the **Year** (e.g., `22` = 2022, `24` = 2024).
* **Digits 10 & 11** represent the **Month** (e.g., `03` = March, `11` = November).
> **Example Breakdown:**
> If your serial number looks like `XXXXXXX2305012`:
> * `2305` represents **May 2023**
> * `012` means it was the 12th unit of that model built during that month.

If you ever need to verify the exact production day or pull the original testing cards for warranty tracking, you can always drop a quick email to Bryston service with your 14 digits, and they can pull up its exact build history.
