Brimar Thermionic Products 12AX7 long plate dual triode has been selected for its high gain, and is most suitable for musical instrument pre-amp applications. With its long plate, spiral filament and rugged design, it has a smooth bite that musicians crave for.

Just like in the days of old British valve manufacturers would select certain vacuum tubes and mark them as ‘foreign’ we believe this is a worthy contender for the ‘modern’ 12AX7 as it provides somewhat more gain than its predecessor.

If this product is out of stock, please consider using the ECC83 which is functionally the same with a slightly warmer performance.
