ELECTRO HARMONIX 12AY7-6072A TUBE

The tubes we sell are specially selected for their low noise and microphonics.

Tubes that don’t guarantee the correct noise level for use in microphones are rejected. That’s why we test each tube individually by hand before shipment.

These tubes come with a 30 days performance guarantee; if one fails or becomes noisy within 30 days, we replace it under warranty, on condition that you return it to us.

These tubes are ideal for upgrading tube microphones of various brands.
