6L6
Brimar thermionic products 6L6 Beam Power Tetrode is ideal for
high-output audio amplifiers and offers excellent sonic performance.
This 6L6 is of rugged construction, lush in sound with extraordinary
dynamics, stability and reliability. It has a triple anode for superior
dissipation, excellent grid/screen alignment that’s fully ‘screen aged’
and it can be operated upright or inverted. Our choice of 6L6 was
difficult as the original Brimar is a hard act to follow. With
everything considered the Brimar thermionics 6L6 is a very close
facsimile that is highly musical and cost effective.
