Boulder 3010 Preamplifier

The 3010 is the flagship preamplifier in Boulder's 3000 Series, a fully balanced, two-chassis design with the audio circuitry and power supply in separate enclosures.

It uses separate left and right analog sections with individual power supplies for each channel plus control and standby, isolating control and power circuitry from the audio path, built around a matched, dual-phase 993SD gain stage for improved thermal tracking.
