The Brimar CV4004 is an excellent UK made 12AX7 with a quasi boxed anode. Long plate construction, superb for phono stages, hifi, and guitar amps! We have a limited supply of low noise selected tubes, as well as Brimar CV4004 with balanced sections. $119.99 per tube!
The India made BEL 12AX7 is by far the best value in 12AX7 tubes. Made on Philips Mullard equipment and identical to a mullard 12ax7, but pumped in India, these have the exceptional tone of a Mullard and accentuated mids without the hefty price tag. Branded BEL or other branding. All remaining stock has balanced sections (both triodes measure equally)$79.99 per tube
