🎶✨ Proton AA-1150 Stereo Power Amplifier — Serviced, Cleaned, Large Dual Green dB Output Meters, Power Envelope Design, Bench Tested

Here is a clean, serviced Proton AA-1150 stereo power amplifier, featuring the classic large dual green decibel output meters and Proton’s well-known Power Envelope amplifier design.

The AA-1150 is rated at approximately 50 watts per channel, but like many Proton/NAD-era designs, it was built with strong dynamic headroom and real-world drive capability. The oversized green meters give this amplifier a distinctive vintage look and make it a great match for a classic preamp, rack system, or dedicated two-channel setup.

This unit has been serviced, cleaned, detailed, and bench tested by Bash Vintage Audio. It is working properly and presents well for a vintage power amplifier from this era.
