Vintage Design M87D Swedish Class-A Transformer Mic Preamp – 80dB Gain – Excellent

The Vintage Design M87D is a discontinued single-channel Class A microphone and instrument preamp designed and built in Sweden. It features a transformer-balanced output and up to 80 dB of gain, making it suitable for low-output dynamic and ribbon microphones as well as condensers.

Condition

Excellent cosmetic condition. During testing, I noticed a slight, brief pop in the audio when moving the stepped input gain selector from 0 to 5. The signal is stable at settings above 5. The selector had been left at 0 for an extended period, and the cause of the pop is unconfirmed.

Features

• Single-channel Class A preamp with transformer-balanced output
• Stepped input gain selector and independent output level control
• Up to 80 dB of gain with a switchable 30 dB boost
• Selectable microphone input impedance of 300 or 1,200 ohms

• AIR switch for high-frequency enhancement
• Hi-Z instrument input
• XLR and ¼-inch connections

A rare opportunity to acquire a boutique Swedish microphone preamp known for its exceptional sound quality and professional build standards.
