All EL84 include our 6 month replacement warranty.
For best results replacing 7189, we suggest Sovtek EL84-M, or JJ EL84.
Sovtek EL84 Standard grade EL84/6BQ5, fine for old radios, etc, also Standard issue in many new amplifiers.
JJ 6BQ5/EL84 A best buy, good tone and reliability for a very reasonable price.
7189/EL84M Sovtek A heavy duty EL84 that's a good replacement for 7189 as well. These sound a little more powerful in EL84/6BQ5 applications. Used by Matchless.
