Art Audio only sells Grade A Tubes from Sophia Electric in matched pairs or quads.
This new blue glass 6SN7 has rich tonality and big sound stage. Designed to compliment to Aqua 274B and Classic 300B tubes, the new 6SN7 is a great choice to replace vintage 6SN7 tubes in all tube pre-amplifiers and tube amplifiers.
Art Audio does not stock Sophia Tubes but Sophia will drop ship directly to you for us. Free Shipping on all order and they typically ship within 48 hours.
We do need to check inventory. If Sophia is out-of-stock you will receive a full refund.
