Most are labeled and boxed as RCA. NOS in original boxes.
Great US made tube for all EL84 applications. Great in guitar amps (Vox AC15, AC30, Dr Z, Matchless, etc) and audiophile amps.
Mike: The GE EL84s sound awesome in the Marshall 2061X. I also put the other RFT in the V1 position and the difference in the tone is amazing, It is night and day. I had been using JJ 84
Hi Mike, I just want to thank you for such great service. These NOS GE EL84's in my Dr Z Stang Ray are fantastic. A really nice upgrade from using the JJ's - THANKS AGAIN - t.y.
These sound FANTASTIC in my AC30 hand wired amp and 65 Amps Marquee. Thank you!
