Condition: Very Good
Brand: Optimus (Radio Shack)

🔊 Description

Compact, clean, and surprisingly useful—the Optimus SA-155 is a small integrated stereo amplifier that’s found a second life in today’s vinyl resurgence.

With turntables back in a big way, this little amp is a perfect budget-friendly solution for powering a simple vinyl setup, especially in smaller spaces like bedrooms, offices, or apartments.

🎶 Why it’s great for vinyl setups

• Ideal for entry-level turntables with built-in phono preamps
• Clean, simple signal path—no unnecessary extras
• Perfect for bookshelf speakers in a small room
• Great for desktop listening or a secondary system

👉 If you’ve got a turntable with a line-level output, this is an easy, affordable way to bring it to life.

⚙️ Features

• Compact integrated stereo amplifier
• Approx. 1.8 watts per channel (best suited for efficient speakers)
• RCA inputs (plug-and-play with most modern turntables w/ preamp)
• Headphone output for private listening
• Simple, no-nonsense controls

🧠 Real-World Use

This is not a high-power amp—but that’s not what it’s for.

It shines in:

• Small-room vinyl setups
• Desktop audio rigs
• Garage / workshop systems
• Testing gear on the bench

📦 Condition

• Fully functional
• Clean overall with light cosmetic wear consistent with age
• All knobs and inputs working as expected

💡 Notes
