Are sovtek EL84 tubes any good?
Sovtek EL84 – The Sovtek EL84 has been a staple for Fender, Boogie, Crate, Peavey and other manufacturers of tube amps using the ’84. This tube really is a good value. It is predictable, reliable and affordable. You can get good EL84 tone at a reasonable price.
Are Groove Tubes any good?
