The ultimate 6L6GC tube for guitar and audiophile applications where clean power is required. Great tone. Nice original boxes. Some tubes labeled and boxed as RCA. One matched pair labeled and boxed as RCA.
NOS in original boxes.
"Hi Mike: I got the RCA 5751 you sent me in the mail on Saturday. The improvement in tone (over a 12-AX7) was amazing. It gives my strat loads of texture when played clean, and the 335 is sounding great, even at high volumes (Super Reverb Reissue). Thanks, Kurt E."
