7581

7581A's are an industrial/military version of the 6L6GC which is rated for higher power (35 versus 30 watts) than 6L6GC's. Very durable and long lasting with great tone. Great in any 6L6 type amplifier where maximum clean headroom is desired. Excellent in Fender Twin Reverbs, Pro Reverbs, Super Reverbs, other Fender 6L6 type amps and clones, new Traynor 6L6 amps. These are also an excellent and less expensive alternative to 7027 tubes in Ampeg and other amps.
