SAE (Scientific Audio Electronics) For Sale

At Frotronics, we strictly sell the absolute best of the SAE line: the legendary components proudly engineered and manufactured right here in the USA. We focus exclusively on the "MARK" and "00" series.

Please note: We are completely sold out of the Professional Series.

 

🛠️ Custom Restoration On Request

We do not sell unserviced or original-condition gear. To ensure peak audiophile performance and lifelong reliability, all available inventory is sold as a custom restoration project on a per-request order basis only.

We currently have a select stock of the following chassis ready for your custom build:

• Power Amplifiers ("MARK" & "00" Series): Most models in stock, including select rare models and the big WPC 2500 & 2600.

• Preamplifiers ("MARK" & "00" Series): Limited inventory available.

• Tuners ("MARK" & "00" Series): Only 8000 left in stock.

• Equalizers ("MARK" & "00"): Currently out of stock.

 

Payment Terms: All custom restorations must be paid in full before work begins. A 50% deposit is required to secure the unit and place you in our bench queue.

 

🚫 Excluded Series & Inventory Restrictions

To protect our customers and uphold our restoration standards, we do not sell, stock, or service any other SAE lines. This includes the following series:

• "01" Series (part of the computer direct-line series)

• "02" Series (part of the computer direct-line series)

• "X" Series

• "Two" Series

 

Why we draw this line: These later series rely on specialized, proprietary digital and computer architecture. Many of the parts in these units are obsolete, entirely unobtainable, and lack modern replacements. Because we refuse to sell gear that cannot be perfectly serviced or backed by our high standards and warranty, we stick strictly to the bulletproof, fully rebuildable analog American classics featuring modern upgraded components.
