Product Details

Electro-Harmonix 6550 EH Vacuum Tube Duet Platinum Matched
The 6550EH is the finest current production tube for any amp using 6550 or KT88. The 6550EH offers the maximum power of any 6550 with the linearity guitar and bass players want. With 42 watts of plate dissipation in tetrode operation and 44 watts in triode, the 6550EH offers an improvement in power over even the most desirable vintage types including the Tung-Sol 6550 and Genelex KT88. This extra headroom in a 6550EH equipped amp means bass players can finally realize the full dynamic range of the instrument and the sweetest tone available. The extra ruggedness of the 6550EH was engineered with the punishing abuse of guitar amps in mind. The nickel steel side rod mica supports ensure that the 6550EH will hold up in even the most punishing environment of high powered bass amps like the Ampeg SVT and combos where the tube is only inches from the speaker, and still deliver the sweetest tone of any 6550 or KT88. The 6550EH will greatly improve the performance of any amp using 6550's but can also replace the KT88 in any application. Matching power tubes for equal current draw is important for maximum performance. Electro-Harmonix's platinum matching process consists of a 24 hour tube burn-in period followed by a bias (plate) current measurement in milliamps to ensure accurate matching.

Reviews

Electro-Harmonix 6550 EH Vacuum Tube Duet Platinum Matched
Electro-Harmonix 6550 EH Vacuum Tube Duet Platinum Matched is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Outstanding 6550I was given a quad of these to try out in a new amp that came with a quad of Sovtek KT88's. Some of the Soveteks, for what ever reason, ran with a slight redness but sounded fine. These EH 6550's are quite an improvement over the Sovteks. Much better range and depth and more head room as well. After a few hours of run time, they hold bias perfect.They are being used in a Bob Latino built Dynaco ST120 @ 60wpc. OUTSTANDING tube.
