A military-spec version of the standard Sovtek EL84 - the Sovtek EL84M's extended voltage tolerance - improved plate dissipation - and rugged construction make it equivalent to the RCA 7189. Chosen by Matchless for their designs - the EL84M also features higher transconductance - more power - and longer life than the less expensive EL84 - making it perfect for hi-end audio applications. However - many musician's prefer the regular EL84's warm distortion to the EL84M's tighter - cleaner tone. For all Hi-Fi users - the EL84M is definitely the tube of choice. Printing may be different depending on availability of stock.
