QUAD Four Factory Platinum Matched SOVTEK EL84M EL84 Tubes 24Hr Burn-in NEW

Description

Brand new, factory matched Quad (4) SOVTEK EL84M .   The SOVTEK EL84M is 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.
NOTE: Due to the larger diameter of the glass envelope, this EL84 will NOT fit in the following amplifiers:
BadCat Model 2R
Bad Cat Amplifier Model Black Cat
Marshall DSL201
Marshall DSL401
VOX reissue AC15
These are factory tested at real world operating voltages and matched for current and transconductance.  You will not be disappointed in the performance of these tubes.
They are burned in for 24 hours and then platinum matched by the factory at 250V plate, 250V screen and -8.6V bias.
Insist on factory platinum matched tubes for best performance.
They are shipped in factory retail boxes and labelled with factory matching statistics as shown.
All tubes carry the 90 day factory warranty against defects from date of purchase.
